How to get exit value 1

[kubatk]

Hello everybody,
I run an external program from FP 2.5 DOS application using RUN/! command and need to get exit value of that program.
One solution could be running BATCH file instead of EXE directly and test ERRORLEVEL, save it into a file which could then be read in FP application.
But this seems to me rather complicated and "not very nice".
Has somebody more simple and straightforward solution?
Thanks for your help.

I agree that a batch file isn't the most elegant of solutions but it works and it's reliable. You don't say which operating system you're using but I suspect you'll find it difficult to delve into the API of something like Windows XP from a 12-year-old program.

If the external program is written by you, you could use the following simple method.
Create a text file containing one word "failure" in Foxpro.
Have your external program change that word to "Success" having successfully completed. When control is returned to Foxpro, ask Foxpro to check that the word is "Success" in the text file.

Thank you both for the answers.
I wrote that application many years ago, it is (still) run on DOS and Windows 98 workstations and now I am forced to do some changes in it .
The program that is run from it isn´t my product.
It is strange that there is no sys() function that could be used!

I tried solving this problem long time ago and I could not find any fox function. I wrote a little EXE program for catch errorlevel.
My program is on

Call: prunprg.exe YourProgram.exe
Return: created prunprg.txt is filled somthing like this:
DOSERROR = 2
DOSEXITCODEL= 0
DOSEXITCODEH= 0

Thanks, this is a better solution than running a batch file and invoking another command.com (dík Tomáši ).
