Probably you are calling bat file with the RUN command from VFP.
If it is the case, then I would try to call the exe file directly from shellexec, like:
DECLARE INTEGER ShellExecute ;
IN SHELL32.DLL ;
INTEGER nWinHandle,;
STRING cOperation,;
STRING cFileName,;
STRING cParameters,;
STRING cDirectory,;
INTEGER nShowWindow

? ShellExecute(0,"open","dosexe.exe","list of parameters","",0)
clear dlls

>It is an EXE, however, it is called from a DOS batch file with parameters. I was sure it was a mem allocation problem. I solved it (apparently) by taking a copy of foxrun.pif,putting it in the working directory of the DOS program I want to run, and changing the "cmd line" to a batch file with the parameters required. I set conventional memory to Auto, initial environment to 512, XMS memory to 1024 and clicked "Uses HMA". In VFP is simply run the pif file.

>>>I have a VFP 6 app that needs to run a dos command. It fails and I think it's because there is not enough conventional memory available. So, I created a PIF file that names the command to run. For memory I set it to 640 (dropdown selection on the memory page). But, when I edit properties I see that it reverts to Auto. There are several memory selections: Conventional, Initial, EMS, XMS, DPMI, protected mode, etc. Not sure what to set here. VFP help refers to KB Required text box in PIF files but I don't see it, just the dropdowns. I'm running Win 2k Pro.
