European Patent Publication Nos. 393 529 Al, 393 530 Al, 393,604 A2, 410 148 Al, 415 304 A2, 429 987 A2, 498 290 Al disclose dipyridodiazepinone derivatives including nevirapine (BI-RG-587) 6,11-dihydro-l l-cyclopropyl-4-methyldipyrido[2,3-b:2',3'-e]- [l,4]diazepin-6-one of Boehringer Ingelheim [BOEHRINGER] are useful for in the treatment of HIV-1 infection alone or in combination with other anti-virals. International Publications Nos. WO 92/00952 and WO 92/00979, and European Patent Publication Nos. 417 840 Al, 0384 522 Al, 336,466 Al, 430 334 Al of Janssen [JANSSEN] discloses various compounds which are useful in the treatment of HIV-1 infection alone or in combination with other anti-virals. These compounds include (+)-(5S)-4,5,6,7-tetrahydro-5- methyl-6-(3-methyl-2-butenyl)imidazo[4,5,l-j ][l,4]benzodiazepin-2(lH)-thione, (+)-(5S)-4,5,6,7- tetrahydro-9-chloro-5-methyl-6-(3-methyl-2-butenyl)imidazo[4,5,l-jk][l,4]benzodiazepin-2(lH)- thione, (-)-α-[(2-nitrophenyl)amino]-2,6-dichlorobenzeneacetamide, (-)-α-[(5-methyl-2- nitrophenyl)amino]-2,6-dichlorobenzeneacetamide, (-)-α-[(2-acetylphenyl)amino]-2,6- dichlorobenzeneacetamide, (-)-α-[(2-acetyl-5-methylphenyl)amino]-2,6-dichlorobenzene- acetamide, α-[(2-acetyl-5-chlorophenyl)amino]-2,6-dichlorobenzeneacetamide, α-[(5-chloro-2- nitrophenyl)amino]-2,6-dichlorobenzeneacetamide, α-[(2-acetyl-5-fluorophenyl)amino]-2,6- dichlorobenzeneacetamide. A major problem in treating HIV infected individuals with nucleoside and non- nucleoside compounds is that virus resistant to the compounds used for the treatment emerges, see J. Virol, 65, 4887 (1991) and Proc. Natl. Acad. Sci., (USA) 88, 11241 (1991). The concept of HIV resistance altering the sensitivity to other drugs within the same chemical class has been reported, Science 353, 1557 (1991). Virology 190, 269 (1992) discusses the antiviral properties of three BHAP compounds and the development of drug-resistant viruses. Further, the article discussed the mutations in the RT gene which leads to amino acid changes in the reverse transcriptase of the resistant strains. Bioorganic & Medicinal Chemistry Letters 2(12), 1745 (1992) disclosed various nevirapine-like compounds including various imidazo[2',3':6,5]dipyrido[3,2-b:2',3'-e]-l,4- diazepines which are HIV-1 reverse transcriptase inhibitors with greater enzyme affinity than nevirapine. The present invention is a method of treating HIV infected individuals which increases the sensitivity of the HTV virus to treatment with various non-nucleoside drugs. SUMMARY OF INVENTION Dislcosed is a method of treating a HIV positive human which comprises (1) administering to the HIV positive individual a sensitizingly effective amount of a SENSITIZING HIV-1 INHIBITOR until increased sensitivity to a NON-NUCLEOSIDE HIV TREATMENT DRUG develops, (2) administering to the HIV positive individual an effective amount of a NON- NUCLEOSIDE HIV TREATMENT DRUG. Also disclosed is a method of treating a HIV positive human which comprises administering to the HIV positive individual a sensitizingly effective amount of one or more SENSITIZING HIV-1 INHIBITOR concurrently with an effective amount of a NON- NUCLEOSIDE HIV TREATMENT DRUG. Further disclosed is a NON-NUCLEOSIDE HIV TREATMENT DRUG to prepare a medicament for treatment of HIV positive individuals having strains of HIV showing increased sensivity thereto due to the administration of a SENSITIZING HIV-1 INHIBITOR. Additionally, disclosed is the use of a NON-NUCLEOSIDE HIV TREATMENT DRUG to prepare a medicament for the treatment of HIV positive individuals concurrently receiving a SENSITIZING HIV-1 INHIBITOR. DETAILED DESCRIPTION OF THE INVENTION Various nucleoside (AZT) and non-nucleoside reverse transcriptase inhibitors are known as being useful for the treatment of HIV infected individuals. With regard to the non-nucleoside reverse transcriptase inhibitors, see for example, European Patent Publication Nos. 484 071 A2, 462,800 A2, 462,808 A2, 481,802 Al, 393 529 Al, 393 530 Al, 393,604 A2, 410 148 Al, 415 304 A2, 429 987 A2, 498 290 Al, 417 840 Al, 0384 522 Al, 336,466 Al, 430 334 Al, US Patent 5,124,327, International Publications Nos. WO 91/09849, WO 92/00952 and WO 92/00979 and Antimicrobial Agents and Chemotherapy, 36, 1019 (1992). With the NON-NUCLEOSIDE HIV TREATMENT DRUGs, it has become apparent that resistance to the pharmaceutical agent rapidly develops reducing or eliminating the efficacy of NON-NUCLEOSIDE HIV TREATMENT DRUGs. The SENSITIZING HIV-1 INHIBITOR compounds of the present invention sensitize the HIV infected individual's HIV to treatment with a NON-NUCLEOSIDE HIV TREATMENT DRUG. It is preferred that the SENSITIZING HIV-1 INHIBITOR, be a BHAP COMPOUND but other HIV-1 RT inhibitors which sensitize HIV infected individuals to treatment with NON- NUCLEOSIDE HIV TREATMENT DRUGs are operable. The BHAP COMPOUNDS are known, see International Publication WO 91/09849. It is preferred that the SENSITIZING HIV- 1 INHIBITOR compound be l-[2-(5-methoxyindolyl)carbonyl]-4-[3-(N-ethylamino)-2-pyridin- yl)piperazine (WO 91/09849, EXAMPLE 16) or l-[2-(5-methanesulfonamidoindolyl)- carbonyl]-4-[3-(N-isopropylamino)-2-pyridinyl]piperazine (WO 91/09849, EXAMPLE 105). The NON-NUCLEOSIDE HIV TREATMENT DRUGs include the MERCK COMPOUNDS, BOEHRINGER COMPOUNDS and JANSSEN COMPOUNDS, PFIZER COMPOUNDS, but other non-nucleoside HIV-1 reverse transcriptase inhibitors are also operable. It is preferred that the MERCK COMPOUNDS be selected from the group consisting of 3-{[(4,7-dichloro-l,3-benzoxazol-2-yl)methyl]amino}-5-ethyl-6-methylpyridin-2(lH)-one, 3-{[(4,7-dimethyl-l,3-benzoxazol-2-yl)methyl]amino}-5-ethyl-6-methylpyridin-2(lH)- one, 3-[2-(benzoxazol-2-yl)ethyl]-5-ethyl-6-methyl-pyridin-2(lH)-one, 5-ethyl-6-methyl-3-(2-phthalimidoethyl)pyridin-2(lH)-one and 3- { [ 1 ,3-benzoxazol-2-yl)methyl]amino } -5-ethyl-6-methyl-pyridin-2(lH)-one. It is preferred that the BOEHRINGER COMPOUND be 6,11-dihydro-l l-cyclopropyl-4- methyldipyrido[2,3-b:2',3'-e]-[l,4]diazepin-6-one. It is preferred that the JANSSEN COMPOUNDS be selected from the group consisting of (+)-(5S)-4,5,6,7-tetrahydro-5-methyl-6-(3-methyl-2-butenyl)imidazo[4,5,l- jk] [ 1 ,4]benzodiazepin-2( 1 H)-thione, (+)-(5S)-4,5,6,7-tetrahydro-9-chloro-5-methyl-6-(3-methyl-2-butenyl)imidazo[4,5,l- jk] [ 1 ,4]benzodiazepin-2( 1 H)-thione, (-)-α-[(2-nitrophenyl)amino]-2,6-dichlorobenzeneacetamide, (-)-α-[ (5 -methyl -2nitrophenyl)amino] -2,6-dichlorobenzeneacetamide , (-)-α-[(2-acetylphenyl)amino]-2,6-dichlorobenzeneacetamide, (-)-α-[(2-acetyl-5-methylphenyl)amino]-2,6-dichlorobenzeneacetamide, α-[(2-acetyl-5-chlorophenyl)amino]-2,6-dichlorobenzeneacetamide, α- [ (5 -chloro-2-nitropheny l)amino] -2 , 6-dichlorobenzeneacetamide , α-[(2-acetyl-5-fluorophenyl)amino]-2,6-dichlorobenzeneacetamide. It is more preferred that the JANSSEN COMPOUND be selected from the group consisting of (-)- -[(2-nitrophenyl)amino]-2,6-dichlorobenzeneacetamide, (-)-α-[(5-methyl-2nitrophenyl)amino]-2,6-dichlorobenzeneacetamide, (-)-α-[(2-acetylphenyl)amino]-2,6-dichlorobenzeneacetamide, (-)-α-[(2-acetyl-5-methylphenyl)amino]-2,6-dichlorobenzeneacetamide, α-[(2-acetyl-5-chlorophenyl)amino]-2,6-dichlorobenzeneacetamide, α-[(5-chloro-2-nitrophenyl)amino]-2,6-dichlorobenzeneacetamide, α-[(2-acetyl-5-fluorophenyl)amino]-2,6-dichlorobenzeneacetamide. It is preferred that the PFIZER COMPOUND be There are a number of ways the sensitizing process of the present invention can be used to treat HIN infected individuals (both asymptomatic and those with AIDS). One method involves treating the HIV infected individual with a SENSITIZING HIV-1 INHIBITOR followed by treatment with a NON-NUCLEOSIDE HIV TREATMENT DRUG. Another method involves concurrent administration of the SENSITIZING HIV- 1 INHIBITOR and NON-NUCLEOSIDE HIV TREATMENT DRUG. The first method involves treating the HIV infected individual with a SENSITIZING HIV-1 INHIBITOR followed by treatment with the NON-NUCLEOSIDE HIV TREATMENT DRUG. Using this method the HIV infected individual is given a sensitizingly effective amount of one or more SENSITIZING HIV-1 INHIBITORS until increased sensitivity to a NON-NUCLEOSIDE HIV TREATMENT DRUG develops. This is then followed by administering to the HIV positive individual of an effective amount of a NON-NUCLEOSIDE HIV TREATMENT DRUG. The increased sensitivity to the NON-NUCLEOSIDE HIV TREATMENT DRUG can be determined clinically and/or in vitro. Utilizing the clinical method, the HIV positive individual will have increased sensitivity to the NON-NUCLEOSIDE HIV TREATMENT DRUG when resistance develops to the SENSITIZING HIV-1 INHIBITOR. Hence, when the clinician notices resistance developing to the SENSITIZING HIV-1 INHIBITOR, the increased sensitivity to the NON-NUCLEOSIDE HIV TREATMENT DRUG will have occurred and the administration of the SENSITIZING HIV-1 INHIBITOR can be stopped and the administration of the NON-NUCLEOSIDE HIV TREATMENT DRUG can be started. Alternatively, the increased sensitivity to the NON-NUCLEOSIDE HIV TREATMENT DRUG can be measured in vitro by measuring the level of p24 antigen as determined by enzyme-linked immunosorbent assay (ELISA) using any of the number of commercially available ELISA kits. When administration of the SENSITIZING HIV-1 INHIBITOR begins, the level of p24 will decrease. When the level of p24 no longer decreases but begins to increase, the HTV positive individual has become resistant to the SENSITIZING HTV-l INHIBITOR and has increased sensitivity to the NON-NUCLEOSIDE HTV TREATMENT DRUG. An alternative method of determining the HIV positive individual's increased sensitivity is by checking the HTV positive individual's reverse transcriptase for a mutation in the region known to confer resistance to the SENSITIZING HTV-l INHIBITOR and increased sensitivity to the NON-NUCLEOSIDE HTV TREATMENT DRUG. If a mutation from proline to leucine occurs at amino acid 236 of the HTV-l reverse transcriptase, then that individual will have increased sensitivity to the NON- NUCLEOSIDE HIV TREATMENT DRUG. It is also likely that other mutations in this region of reverse transcriptase, for example changes at the amino acid from about 200 to about 275, more particularly at 233, 234 or 238, will confer resistance to the SENSITIZING HTV-l INHIBITOR and sensitization to the NON-NUCLEOSIDE HIV TREATMENT DRUG. These changes can be monitored or detected by means known to those skilled in the art, see for example J. Virol., 65, 4887 (1991); Proc. Natl. Acad. Sci. (USA) 88,11241 (1991); Proc. Natl. Acad. Sci. (USA) 89, 1934 (1992); Journ. of Medical Virology, 37, 241 (1992). The sensitizingly effective amount is an amount that achieves a sustainable blood level which can either be below the MIC of the HIV virus or above the MIC of the HIV virus. It is preferred that the amount be an amount that exceeds the MIC of the HIV virus since selection of the sensitized strains will occur more quickly if the MIC of the organism is exceeded for most of the day. One skilled in the art knows how to monitor the blood level to determine if the amount given is above or below the MIC of the HIV virus and is able to then give an amount which will provide a sustainable blood level. The SENSITIZING HIV-1 INHIBITOR is administered in a dosage range of about 50 to about 3,000 mg per day in a single or divided doses, preferably about 600 to about 2,100 mg per day in divided doses. The SENSITIZING HTV-l INHIBITOR is given for a period of about two to about 16 weeks, preferably about 8 to about 12 weeks before the HIV infected individual is treated with a NON-NUCLEOSIDE HIV TREATMENT DRUG. More preferably, the transition from administration of the SENSITIZING HTV-l INHIBITOR to the NON-NUCLEOSIDE HIV TREATMENT DRUG is measured either clinically and/or in vitro as discussed above. For example, if the SENSITIZING HIV-1 INHIBITOR is l-[2-(5-methoxyindolyl)carbonyl]-4-[3-(N- ethylamino)-2-pyridinyl)piperazine, an HTV infected individual would be treated with a dose of 3-10 mg/kg orally three or four times daily for 8-12 weeks; if the SENSITIZING HTV-l INHIBITOR is l-[2-(5-methanesulfonamidoindolyl)carbonyl]-4- [3-(N-isopropylamino)-2-pyridinyl]piperazine, an HTV infected individual could be treated with a dose of about 0.5 to about 5 mg/kg/dose orally two to four times daily, this would be followed by a NON-NUCLEOSIDE HIN TREATMENT DRUG. Following treatment with SENSITIZING HIV-1 INHIBITOR, the sensitized strains would then be more sensitive to the NON-NUCLEOSIDE HTV TREATMENT DRUG. The dosages of the NON-NUCLEOSIDE HTV TREATMENT DRUG are known to those skilled in the art. The dosage range is from about 50 to about 4,000 mg per day in either a single or divided doses depending on the particular compounds, preferably from about about 50 to about 2,000 mg. If the NON-NUCLEOSIDE HIV TREATMENT DRUG is a MERCK COMPOUND, it is preferably administered orally in a dosage range of from about 50 to about 2,000 mg, more preferably from about 200 to about 800 mg, one to three times daily. If the NON-NUCLEOSIDE HTV TREATMENT DRUG is a BOEHRINGER COMPOUND, it is preferably administered orally in a dosage range of from about 50 to about 2,000 mg, more preferably from about 50 to about 500 mg per day in a single or divided doses, still more preferably from about 100 to about 200 mg per day as a single dose. If the NON-NUCLEOSIDE HIV TREATMENT DRUG is a JANSSEN COMPOUND it is preferably administered from about 50 to about 2,000 mg, more preferably from about 100 to about 2,000 mg per day either orally in divided doses or by continuous IV infusion depending on the particular compound. More specifically, if the JANSSEN COMPOUND is (+)-(5S)- 4,5,6,7-tetrahydro-9-chloro-5-methyl-6-(3-methyl-2-butenyl)imidazo[4,5,l- jk][l,4]benzodiazepin-2(lH)-thione, it is administered continuously IV in a total daily dose of from about 50 to about 1,000 mg daily. More specifically if the JANSSEN COMPOUND is (-)-α-[(2-acetylphenyl)amino]-2,6-dichlorobenzene- acetamide, it is administered orally in a total daily dose of from about 100 to about 2,000 mg in divided doses two to six times daily. With this method one or more than one SENSITIZING HIV-1 INHIBITOR can be used, likewise one or more than one NON-NUCLEOSIDE HIV TREATMENT DRUG can be used. This method can involve a multiple of treatment cycles as is known to those skilled in the art. Further, a modified form of this method is after the sensitivity to the NON-NUCLEOSIDE HTV TREATMENT DRUG has increased by the initial administration of the SENSITIZING HTV-l INHIBITOR, is to administer the SENSITIZING HTV-l INHIBITOR and NON-NUCLEOSIDE HTV TREATMENT DRUG concurrently rather than terminate the SENSITIZING HIV-1 INHIBITOR. Another alternative form of this method is after the initial administration of the SENSITIZING HTV-l INHIBITOR to increase the HIV positive individual's sensitivity to the NON-NUCLEOSIDE HIV TREATMENT DRUG, is to administer the SENSITIZING HTV-l INHIBITOR intermittently with administration of the NON- NUCLEOSIDE HIV TREATMENT DRUG to reduce the probability that the increased sensitivity does not disappear. The other method of treatment involves initially treating the HIV infected individual with a SENSITIZING HTV-l INHIBITOR concurrently with the NON- NUCLEOSIDE HIV TREATMENT DRUG. Using this method the HTV infected individual is given both the SENSITIZING HTV-l INHIBITOR and NON- NUCLEOSIDE HIV TREATMENT DRUG simultaneously. The therapeutic dosage range and frequency of administration of both the SENSITIZING HIV-1 INHIBITOR and NON-NUCLEOSIDE HIV TREATMENT DRUG is the same as for administration of the NON-NUCLEOSIDE HIV TREATMENT DRUG following administration of the SENSITIZING HTV-l INHIBITOR, the only thing that is different is the sequencing of when the SENSITIZING HIV-1 INHIBITOR and NON-NUCLEOSIDE HTV TREATMENT DRUG are given. A modification of this process is that after a period of time when increased sensitivity to the NON-NUCLEOSIDE HTV TREATMENT DRUG is obtained, the SENSITIZING HTV-l INHIBITOR is given intermittently with the NON- NUCLEOSIDE HTV TREATMENT DRUG rather than continuously. The particular method to be utilized with an particular patient will depend on many factors as will be apparent to those skilled in the art. These factors include whether the patient is symptom free or has some symptoms. Further, if the patient has symptoms are they mild or severe. In addition, other diseases/conditions that affect the patent can enter into the decision as to which method to use in a particular case as is known to those skilled in the art. The exact dosage and frequency of administration depends on the particular SENSITIZING HTV-l INHIBITOR and NON-NUCLEOSIDE HTV TREATMENT DRUG used, the particular condition being treated, the severity of the condition being treated, the age, weight, general physical condition of the particular patient, other medication the individual may be taking as is well known to those skilled in the art and can be more accurately determined by measuring the blood level or concentration of the SENSITIZING HTV-l INHIBITOR in the patient's blood and/or the patient's response to the particular condition being treated. DEFINITIONS AND CONVENTIONS The definitions and explanations below are for the terms as used throughout this entire document including both the specification and the claims. I. CONVENTIONS FOR FORMULAS AND DEFINITIONS OF VARIABLES The chemical formulas representing various compounds or molecular fragments in the specification and claims may contain variable substituents in addition to expressly defined structural features. These variable substituents may be identified by a letter or a letter followed by a numerical subscript, for example, "Z j " or "R j " where "i" is an integer. These variable substituents are either monovalent or bivalent, that is, they represent a group attached to the formula by one or two chemical bonds. For example, a group Z j would represent a bivalent variable if attached to the formula CH^-C^Z j . )H. Groups R_ j and R: would represent monovalent variable substituents if attached to the formula CH^-C^- R j XR -H. When chemical formulas are drawn in a linear fashion, such as those above, variable substituents contained in parentheses are bonded to the atom immediately to the left of the variable substituent enclosed in parenthesis. When two or more consecutive variable substituents are enclosed in parentheses, each of the consecutive variable substituents is bonded to the immediately preceding atom to the left which is not enclosed in parentheses. Thus, in the formula above, both R j and R- are bonded to the preceding carbon atom. Also, for any molecule with an established system of carbon atom numbering, such as steroids, these carbon atoms are designated as C j , where "i" is the integer corresponding to the carbon atom number. For example, Cg represents the 6 position or carbon atom number in the steroid nucleus as tradition- ally designated by those skilled in the art of steroid chemistry. Likewise the term "R 6 " represents a variable substituent (either monovalent or bivalent) at the C 6 position. Chemical formulas or portions thereof drawn in a linear fashion represent atoms in a linear chain. The symbol "-" in general represents a bond between two atoms in the chain. Thus CH 3 -O-CH 2 -CH(R j )-CH3 represents a 2-substituted-l-methoxypropane compound. In a similar fashion, the symbol "=" represents a double bond, e.g., CH 2 =C(R i )-O-CH 3 , and the symbol "≡" represents a triple bond, e.g., HC≡C-CH(R j )- CH 2 -CH 3 . Carbonyl groups are represented in either one of two ways: -CO- or -C(=O)- , with the former being preferred for simplicity. Chemical formulas of cyclic (ring) compounds or molecular fragments can be represented in a linear fashion. Thus, the compound 4-chloro-2-methylpyridine can be ~_- :$; represented in linear fashion by N =C(CHg)-CH=CCl-CH=C H with the convention that the atoms marked with an asterisk (*) are bonded to each other resulting in the formation of a ring. Likewise, the cyclic molecular fragment, 4-(ethyl)-l-piperazinyl can be represented by -N*-(CH 2 ) 2 -N(C 2 H 5 )-CH 2 -C*H 2 . A rigid cyclic (ring) structure for any compounds herein defines an orientation with respect to the plane of the ring for substituents attached to each carbon atom of the rigid cyclic compound. For saturated compounds which have two substituents attached to a carbon atom which is part of a cyclic system, -C(X j )(X 2 )- the two substituents may be in either an axial or equatorial position relative to the ring and may change between axial equatorial. However, the position of the two substituents relative to the ring and each other remains fixed. While either substituent at times may lie in the plane of the ring (equatorial) rather than above or below the plane (axial), one substituent is always above the other. In chemical structural formulas depicting such compounds, a substituent (X j ) which is "below" another substituent (X 2 ) will be identified as being in the alpha (α) configuration and is identified by a broken, dashed or dotted line attachment to the carbon atom, i.e., by the symbol " " or "...". The corresponding substituent attached "above" (X 2 ) the other (X j ) is identified as being in the beta (β) configuration and is indicated by an unbroken line attachment to the carbon atom. When a variable substituent is bivalent, the valences may be taken together or separately or both in the definition of the variable. For example, a variable R j attached to a carbon atom as -C(=R j )- might be bivalent and be defined as oxo or keto (thus forming a carbonyl group (-CO-) or as two separately attached monovalent variable substituents -R j and B-R j .^- When a bivalent variable, R j , is defined to consist of two monovalent variable substituents, the convention used to define the bivalent variabl is of the form "α-R j _ :β-R j _ k " or some variant thereof. In such a case both α-R j.j and β R j _ k are attached to the carbon atom to give -C(α-R j _:)(β-R j _ k )-. For example, when the bivalent variable Rg, -C(=Rg)- is defined to consist of two monovalent variable substit¬ uents, the two monovalent variable substituents are α-Rg_ | .β-Rg_ 2 , .... etc, giving -C(α-R 6 . 1 )(β-R 6.2 )-, .... -C(a-R 6 _ 9 )(B-R 6 _ j0 )-, etc. Likewise, for, the bivalent variable R^, -C(=R 11 )-, two monovalent variable substituents are α-R j j j β- RJ J_ 2 . For a ring substituent for which separate α and β orientations do not exist (e.g. due to the presence of a carbon carbon double bond in the ring), and for a substituent bonded to a carbon atom which is not part of a ring the above convention is still used, but the α and β designations are omitted. Just as a bivalent variable may be defined as two separate monovalent variable substituents, two separate monovalent variable substituents may be defined to be taken together to form a bivalent variable. For example, in the formula -CJ(RJ)H-C 2 (RJ)H- (C j and C 2 define arbitrarily a first and second carbon atom, respectively) R j and R: may be defined to be taken together to form (1) a second bond between C j and C 2 or (2) a bivalent group such as oxa (-O-) and the formula thereby describes an epoxide. When R j and R: are taken together to form a more complex entity, such as the group - X-Y-, then the orientation of the entity is such that C j in the above formula is bonded to X and C 2 is bonded to Y. Thus, by convention the designation "... R j and R are taken together to form -CH 2 -CH 2 -O-CO- ..." means a lactone in which the carbonyl is bonded to C 2 . However, when designated "... R: and R j are taken together to form - CO-O-CH 2 -CH 2 -the convention means a lactone in which the carbonyl is bonded to C j . The carbon atom content of variable substituents is indicated in one of two ways. The first method uses a prefix to the entire name of the variable such as "C j - C 4 ", where both "1 " and "4" are integers representing the minimum and maximum number of carbon atoms in the variable. The prefix is separated from the variable by a space. For example, "C j -C 4 alkyl" represents alkyl of 1 through 4 carbon atoms, (including isomeric forms thereof unless an express indication to the contrary is given). Whenever this single prefix is given, the prefix indicates the entire carbon atom content of the variable being defined. Thus C 2 -C 4 alkoxycarbonyl describes a group H~- (CH 2 ) n -O-CO- where n is zero, one or two. By the second method the carbon atom content of only each portion of the definition is indicated separately by enclosing the "C j -Cj" designation in parentheses and placing it immediately (no intervening space) before the portion of the definition being defined. By this optional convention (C j - C 3 )alkoxycarbonyl has the same meaning as C 2 -C 4 alkoxycarbonyl because the "C j -C " refers only to the carbon atom content of the alkoxy group. Similarly while both C 2 -C 6 alkoxyalkyl and (C j -C3)alkoxy(C j -C 3 )alkyl define alkoxyalkyl groups containing from 2 to 6 carbon atoms, the two definitions differ since the former definition allows either the alkoxy or alkyl portion alone to contain 4 or 5 carbon atoms while the latter definition limits either of these groups to 3 carbon atoms. While the above method of defining variable substituents and the number of carbon atoms in various groups is used to define the BHAP COMPOUNDS, it must be realized that there are alternative methods which accomplish the same thing. Admittedly, the specification and claims here are a composite of information obtained electronically from different sources and therefore represents various styles. Never-the- less, one skilled in the art will certainly know what is being disclosed and/or claimed. When the claims contain a fairly complex (cyclic) substituent, at the end of the phrase naming/designating that particular substituent will be a notation in (parentheses) which will correspond to the same name/designation in one of the CHARTS which will also set forth the chemical structural formula of that particular substituent.
