Having progress from the Z88 to the HP95 I was not impress when I 
discovered that it was not possible to have more than one copy of the 
Memo Editor, or any other application, open at once. On the Z88 it is 
possible to have multiple copies of any application open, a feature which 
I found invaluable and miss.

Having recently got HP's Dictionary/Thesaurus for my 95, a truly 
excellent product, I was of course curious about how it worked and 
inspected the rom card with the Filer, particularly as you just plug the 
card in and three new System Manger Function magically appear. No re-boot 
required!

On the rom card (Drive A:) there are 27 files with a total of 2004924 
bytes. The four most interesting files are APNAME.LST, MEMODICT.EXM (New 
Memo), DICTTHES.EXM (Dictionary/Thesaurus) and HANGMANR.EXM (Hangman 
Game).

Any way to cut a long story short I realized that I now had access to a 
Memo Editor (.EXM) file, enabling me to run a second copy of the Memo 
Editor. This I have done and at first sight there appears to be no 
problems, perhaps Everett advise on any potential ones.

What I did was to add the line "A:\MEMODICT.EXM,BE00,New Memo II" at the 
bottom of my APNAME.LST file in C:\_DAT, re-booted the machine and 
presto, I could start up a second copy of the Editor by pressing CTRL-
{MEMO}.

A word of caution "CTRL-{MEMO} (BE00)" is also used with the Hangman 
Game, in my case it was ok because adding the new line made 9 
applications, and it was the 9th application (Hangman) in the rom card 
that dropped off the end. If this is not the case you will need to pick 
another hot key.

The order for loading System Manager Compliant Applications, far as I 
know are:

1. the built in functions. (8 in all)
2. the ones in C:\_DAT\APNAME.LST, if it exists.
3. the ones in A:\APNAME.LST, if it exists.

Only the first 8 applications are taken from 2 & 3.
If a Hot Key occurs more than once the last instance is used, this allows 
the overriding of the built in functions.
On my machine the 1/2 Meg. model if the System Manger cannot find a file 
it stops and no further applications are not loaded (therefore make sure 
the Second Memo editor is the last line in your APNAME file in case the 
Dictionary card is not plugged in), I understand this has been fixed in 
the new 1 Meg. models.

Everett, if I've got the wrong end of the stick, please would you correct 
me.

PS. I would not advise using the same method on other System Compliant 
applications, even if the .EXM files were available, as the environment 
files (only one copy for each application) are more complex and sometimes 
contain the current file name. This would give unpredictable results and 
could cause file mangling.
