I calling a batch file using the Turbo-C system() call. Is there a way
to get the value of "ERRORLEVEL" upon returning to the Turbo-C program?
system() is declared as an int, but it only returns 0 or -1, I believe
it returns -1 only if it couldn't find COMMAND.COM (and maybe -1 if the
batch file wasn't found, but I haven't tested it for that)  I can't set
an environment variable in the batch file because when I return to the
calling program, that environment is gone. 

I'd appreciate any suggestions
