I am required to load a mouse driver (MOUSE.COM) in RAM for many of
my application programs (XtreePro Gold, PCWrite, etc.).  In order to
utilize the maximum amount of RAM, I load the MARK utility in memory
first and then the mouse driver with a command like the one below:
C:\UTIL\MOUSE C:\MENUS\XTREE.MNU.  Finally, I load the application
program (Xtree, in this case).  The last line in my XTREE.BAT batch
file is RELEASE that unloads all TSRs loaded in RAM after MARK.
 
I use the same technique to load any program that requires a mouse
driver.  The problem is every time this batch file is executed, one
file handle gets tied up.  In the previous exmple, we would have one
file handle associated with XTREE.MNU tied up.  If a run Xtree.bat
again, more file handle, one for every run and each associated with
Xtree.mnu, will get tied up.

I need to be able to use as much RAM as possible *without* tying up
file handles like this.  Any ideas/solutions ?

I use a Compuadd 286/12 with 640K, and 384K extended memory (mostly
used up), running MS-DOS 3.3.

If you prefer, please respond to me directly at FF76@UNTVM1.BITNET
and if I have useful responses, I'll summarize.

Thanks in advance.     - Jhinuk.
