return value from exe

[John Goche]

Hello,

I would like to inspect the exit value of an exe launched from a DOS
prompt. This is the return value as in the 0 in the following C
program:

int main()
{
return 0;
}

On unix one can enter "eacho $?" at the shell prompt to retrieve this
value after the exe completed. Is there a way to do the same thing
from DOS?

Thanks,

JG

You could use a batch file to lauch the exe and catch the return value with
errorlevel. I am not very proficient with batch files but if you go to the
page below and click on "Batch files" then "Errorlevels", you may find what
you need. You could also do this with a scripting language like Python.
