I am not a DOS user, I mostly program in a UNIX or MAC environment, but I
can make a logical guess as to your problem.  Remember that C strings use
the backslash '\' character as an 'escape' character.  In your example,
the '\c' is probably being interpreted as simply the ASCII letter 'c' since
I don't think there is a a MSC interpretation for that sequence.  Anyway,
what you probably need to do is use two backslashes so that the second
one would be taken literally as in:

	execl("\\command.com", "tryit.bat", NULL);

Also, my understanding is that MSC understands the RIGHT way :-) to delimit
directories in a pathname and will handle 'forward slashes.'  Thus, an
alternative would be:

	execl("/command.com", "tryit.bat", NULL);
