Perhaps the backslash is causing the following c to be interpreted literally
as a c, i.e., as though the backslash weren't there at all.

I.e. it's actually doing the same as

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

which looks in the current dir, not in the root dir, for command.com.

replace the single backslash with a double backslash, and the first will
cause the second to be interpreted literally _by_the_compiler_...

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

now the string itself will contain the backslash.
