	Sorry for posting this, I have trouble mailing to UUCP sites.

	There are at least two errors in the above line:

		1) if you want to specify the root directory "\",
		you will have to use the escape sequence "\\" in
		the first argument to execl (re: K&R 1ed p.180)

		2) you are using "tryit.bat" as the first argument
		to command.com; this doesn't do what you want it to

	Why not use:

		system("tryit.bat");

	?? This invokes command.com, and then attempts to locate & run
	your batch file.
