[net.micro] MS-DOS wizardry

Thanks to those of you who responded with suggestions on my problems
with DOS call 4B (EXECute a process).  For those of you who may have
been bitten by this, here's what was doing me in, and the solution:

	The shell, COMMAND.COM, can be invoked with a switch, /C,
	followed by a shell command.  This causes the shell
	to execute the single command and return.  What is
	truly bizarre is that the command line must be terminated with
	a carriage return (D hex), but the count of characters
	in the command line must NOT include the return!
