	 *	no checks exist to enforce upper limits on parameter string lengths.
	 *	This new maximum was reached by calculating the maximum length of
	 *	the job parameter string (presuming each possible qualifier is represented
	 *	once and only once) and tacking on a safety net.  This came to
	 *	10 255 byte strings (plus length byte), 1 longword, and 17 single byte
	 *	identifiers for each of the job keywords.  The maximum of 3000 leaves
	 *	a little room for expansion in the future
