Does someone out there know how to set the DOS errorlevel number in C? I want to write a batch file that can branch according to the value of this number: if errorlevel 1 echo Big... if errorlevel 2 echo Bigger... if errorlevel 3 echo Biggest. Please send code fragments if possible. -- _______________________________________________________________________________ Rodrigo Murillo, University of Colorado - Boulder (303) 761-0410 murillo@boulder.colorado.edu | ..{hao|nbires}!boulder!murillo ( Machines have less problems.

Some C compilers allow you to set the errorlevel with the exit statement as you terminate your program. e.g.: exit(0); for normal exit; exit(x); where x != 0 otherwise. Microsoft C let's you do this. Hoped that helped. /Paul

Re: setting errorlevel from C
For Microsoft C use:
int main(....)
...
{
int rc ;
...
rc = ... ;
...
return rc;
}
Use of exit(rc) would also succeed.

Any program that you might want to port should use exit(rc) to return a non-zero exit code. This is the only method that works under all C compilers and since exit() is quite offen included in the initial object-code module it's not likely to make your program much larger... --- John Stanley (john@viper.UUCP) Software Consultant - DynaSoft Systems UUCP: ...{amdahl,ihnp4,rutgers}!meccts!viper!john
