Oops , i had some old .pif files on my win2k comp (it was orig. upgraded
from win98)  - these used to have a memory setting.
In  win2k the command buffer is fixed at around 2046 bytes.   so you are
going to run in to a problem if you have a large
command line like :

c:\>abc.exe file1.txt file2.txt file3.txt......  file100.txt


windows as such does have a single command line limitation length of 32K ,
the cmd.exe imposes a much smaller limit of 2046 bytes
if you are going above the 32k limit you better rethink the way your app is
written....


i would recommend that you split up your commands into sequential calls
(that might mean changing the way your program works though...)

something like this in a batch file (i assume your files are named
sequentially ...)
for %%d in (1 2 3 4 5 6 7 8 9 10 11...) do abc.exe  file%d.txt

this will  automatically execute it against the files 1 by 1 like this :

c:\>abc.exe file1.txt
c:\>abc.exe file2.txt
....
....
c:\>abc.exe file100.txt


On the other hand , you could also try passing the command line from a
vbscript (wsf windows scripting file) program  or a proper vb
executable......which might overcome the command line length limitation


Set WshShell = CreateObject("WScript.Shell")
'take in the command line file name parameters as an InputBox
'or read in the parameters from an external text file....
strCmdLine = ...the command line params as mentioned above...
' Start the program that is placed in sAddOn
WshShell.Run "c:\\abc.exe" & strCmdLine

the wshshell.run command executes your app under the context of the
cscript.exe interepretr and as such IMO should not suffer from the 2046
byte command.com and cmd.exe limitations....
