I'm looking for some information/advice.

I have a large-ish batch file which I use to run several of my oft-used 
applictions programs.  Recently I noticed that after I ran Dbase VI 1.1 
or Statgraphics (no flames on software choices please :-]) several time 
(about 12 or 13 actually) without rebooting I ran into trouble.   I seem 
to have run out of file handles I use the following batch file to run the 
various applications and return to wherever I was.  Whene I do not use 
the batch file I do not have this problem. 

(I assume this will happen with other software but I haven't had the 
patience to try it.) 

EXAMPLE OF BATCH FILE ROUTINE:

BATCH FILE STARTS 

@ echo off
if %1@==@ goto DEFAULT_PROCESS

for %%g in (LIST-OF-PARAMETERS d D MORE-PARAMETERS) do if %%g==%1 goto %%g
HANDLES NON_LIST PARAMETERS HERE
STUFF
:d                                      
   ECHO PROMPT CD $P>C:\UTL\ZZ1.BAT
   PROMPT $N: 
   COMMAND /C  C:\UTL\ZZ1.BAT >C:\UTL\ZZ2.BAT
   PROMPT $P$G
   c:
   cd \db4
   dbase /t
   CTTY NUL
   COMMAND /C  C:\UTL\ZZ2.BAT
   CTTY CON
   DEL C:\UTL\ZZ?.*
   goto end
MORE_STUFF
:end
END OF BATCH FILE


If I remove the "CTTY NUL" & "CTTY CON" statements, the problem also 
disapppears, so it seems they are slowly  eating up the file handles.

My question is "why?"

Any thoughts?
