I suspect two problems here:

The first, if you are are not using SET EXCLUSIVE ON, is that the file you
are printing to will be locked when you try to read it.  Unless you close it
with the SET PRINTER TO command beforehand.  The low level file functions
Clipper provides do not give any way to open a file in shared mode, and I
would guess that the same is true of the redirection functions (SET PRINTER
TO and SET ALTERNATE TO).

The second problem, and what is the most likely source of what you are
experiencing, is that the file you are writing to is buffered.  Trying to
use MemoRead() to read the file that may not be completely written will not
yield the results you wanted.  I presume you are using these functions to
write a report that a user can scroll through.

Rushmore is sort of a "turbo-access" method.  Foxpro invokes it automatically
when the right conditions apply (suitable indexes on the right fields,
enough memory).  I've heard it's some kind of bit-mapping technique.

It is used by the SQL SELECT optimizer and when you use the "FOR" clause
on various Foxpro commands.  So it's a "set of records" thing--it quickly
retrieves a set of records that match your query, which you can then access
individually, or browse, or print, etc.

To take advantage of it, you want to have an index on each field that will
appear in your SELECT WHERE or FOR clause.  Some people just completely
invert their databases--they put an index on (nearly) every field.  Using
compact structural indexes takes a lot of the sting out of that.

Anyone know more about how Rushmore works?  I'm curious about the details
myself.

Hi,
I have to design a database system for a small office. I dont have any
experience with Paradox but I am required to use Paradox. I have gone
thru the "getting started" manual and it took me only 2-3 hours to get
an idea of what Paradox has to offer (it is easy to use--no doubt!). I 
guess I would have to use PAL. What is the good place to start? I am very
comfortable with programming in several languages and key database issues
in general (have never designed a system though and I only have used SQL).
Also, how long it usually takes to get a grasp of PAL?

Thanks for your help in advance!

Whooaaahh!  Converting by hand wouldn't be so bad, but an automatic
translator will be a real *big* project.  My gut feeling would be 2 real
solid people for 14 months, if they know FoxBase, db-Vista, and C inside
and out with compiler/interpreter experience.

db-Vista alone has several hundred function calls.  You also have to make
sure you've got the C syntax and semantics properly taken care of in you
expression translator.

Generally, systems consultants in the South-East go from $30.00 (entry
level) to $100.00 or more per hour for "high-caliber" senior software
engineers.  A lot depends on who the client is and how scarce the needed
skill is.

1.  Insist on a feasibility study.  Sign a contract with your client for
    this phase.  The result of this will be a project plan, requirements
    specification, functional specs, list of deliverable goods, product
    description, and market analysis.  If you're going to do it by your-
    self, these items can be brief.  Don't make the mistake of wasting
    a lot of your time making up a proposal and having the client say,
    "nah!  Too long or too expensive."

2.  After #1 is done, both you and your client will have a much better
    understanding of the project scope, cost, and timeframe.

There are many good books on consulting and fee structures.  The two major
methods are 'time & materials' and 'fixed price'.

Good luck!

I suggest that part of the reason for the poor response is that
these kind of comparisons are very difficult.  Unless you actually
have applications developed by people with the same level of 
expertise in each product to satisfy the same user requirements, you
don't have a valid basis for comparison, and even then all you can
really compare is the suitability of a particular product for that
application.  Equally, comparing things such as vendor support is
almost impossible, because it is so difficult to set up a valid
comparison.

The comments of enthusiasts for different products do not provide
a valid basis for comparison.

HI,
	Iam involved in a project wherein we transform a particular
	schema in a data model to a equivalent schema in some other
	data model. Schemas are represented either in text or in a  
	graphical form. When the transformation is done from a textual
	form to a graphic representation it is necessary to assign
	coordinates to all the entities in the schema so that they
	can be displayed on the screen using a graphic tool. A algorithm
	which does this has already been developed.

	The schema consists of classes which are represented by means of
	a rectangular block. Relationship between classes are modeled using
	links between the related classes.

	The demands on the alogorithm are as follows :-

		While assigning coordinates it is necessary to make sure that the
	same coordinates are not assigned to more than one class i.e., no classes
	overlap with each other. The links are assigned a starting point and a 
	end point coordinate. The path traversed by a link shouldn't cross a
	already assigned class. Links can cross each other. 

		My question is, has any thing similar to this been done before and 
	and is there any other application for such an algorithm. Please send replies

You _can_, however, imbed two child tables in one master table.  They can
have the same or different linking fields.  This may not be what you need

We use ISDN to connect to the Internet.  It's not a fancy setup; no dial-on-
demand or anything like that.  It's basically a replacement for a dedicated
line.  We use two Fujitsi SRS-410 TAs to connect our Cisco IGS/R to THEnet's
Cisco AGS.  Our TA is configured to simply dial the other TA whenever DTR is
high.

Southwestern Bell's rates make this setup feasible.  Our total monthly charge
for both lines is about $77 (business rates), and there is no per-minute charge
for local calls.  Our SWBT rep told me a while back that long distance data
calls (which are still hypothetical in this area :-) will be charged at the
same rate as voice calls.  Time will tell if that's true or not.

Actually, the rates for most folks will probably be a bit higher.  All of our
Plexar (sp?) lines at Datapoint are already ISDN capabile (2B+D) and cost us
$25 per month.  The remote line at THEnet's POP is part of SWBT's "Digiline"
service.  It costs us just under $42/month for 1B+2 business service.  A second
B channel costs about $8/month if I recall correctly.  Residential rates are
slightly lower, though I don't remember how much.

As far as speed is concerned, we're using a single B channel right now, because
our Fujitsu TAs do not support the combining of the B channels.  We are
supposed to be getting 64 KB per B channel, but SWBT apparently has to upgrade
something first, so we're using 56 KB right now.

The reliability has been excellent.  The lines are very error free.  The Cisco
usually shows less than 5 or 10 CRC errors per week.  In fact, I think most of
those errors occur when THEnet reboots their router early Monday morning,
causing the line to drop.

As for the fun of it, well, it gets us connected to the Internet, and that's
pretty fun :-).

If you mean in the sense of competing-on-demand for switched service, you
are right, with one significant exception. The facilities are not shared,
but they are often multiplexed onto different channels on things like
fiber trunks. (I.e. you will find the bits on the same fiber.)

The exception is interesting: carriers are offering a new type of leased
service that is actually implemented by a dialed call that is then held
up, rather than a fixed administrative ("nailed-up") circuit assignment.
The advantage for the telco is that when one of the legs of the circuit
fails, it is automatically taken out of service, and the leased circuit
automatically grabs another path.

I understand that this type of leased circuit is used for some paths
within PSDNS, and therefore (where the underlying service is ISDN/SS7)
will actually use paths used for voice traffic a moment before. But I
do not think anyone is doing this in dynamic response to offered load.

A PSDN connection is a nailed up circuit (telephone circuit) to a nearby
X.25 switch. You can get them anywhere you can get telephones, for varying
amounts of airmile charges. This even applies to some 3rd world countries,
not just the US. Oklahoma is no problem at all. (You can get access from
Sprint Intl in Moscow and a bunch of other Eastern European cities today.)

Almost all links in the Internet between organizations are leased circuits
run by Internet providers (JvNCnet, NEARnet, PSI, PIPEX, etc). Links within
organizations are of various flavors, including on-demand X.25.

Hi,
Well, I've just heard that we are about to be charged something like $400

This drives me to look for other sources of NT1s.  I don't care if they're
Northern Telecom as long as they talk 2B1Q and talk to a DMS100 talking
2B1Q.  (I was under the impression that the whole point of 2B1Q was to
get vendor independence, but someone has been telling our Campus Telco
office that only Northern NT1s will work.  Is that just smoke, or are we
