*	"mktemp" assumes it is called with a string ending in 6 X's.
*	It will replace the last 6 chars with the process id
*	and a letter (different on each invocation).
*	REALLY "mktemp" replaces everything after the 1st x...
*		this is a feature...
*	Note that the process id does not change under CP/M,
*	therefore the name itself will not be very unique...
*
*	Calling sequence:
*		string = mktemp(string)
*	Where:
*		string -> null terminated string with 6 x's
