COMMENT \

The JSYS table has the following format:

	[ flags
	  ASCIZ/NAME/],,nm

where:

	flags = TBLUK flags
	name = JSYS name
	n = JSYS number
	m = correct table offset to JSYS name for this numeric (JSYS) table
	    offset


As the table is in TBLUK format, it can be accessed by JSYS name
(to get the corresponding JSYS number).  It can also be accessed by
JSYS number (to get the corresponding JSYS name).

 Since offset zero contains the TBLUK table length, care must be
taken to special-case the attempt to index the table numerically
with an index of zero.
