;
;1)	THE ORDER IN WHICH FILES ARE FOUND AND RETURNED TO THE CALLER IS
;	NOT OBVIOUSLY DETERMINISTIC (THE RESULT OF "SYS: 'OR' DSK:" IS
;	A LIST OF DISK STRUCTURES RETURNED BY SYSSTR, WHICH IS IN TURN
;	DEPENDENT OF WHAT UNITS AND WHEN THE VARIOUS DISK STRUCTURES
;	WERE MOUNTED, AND HAS NOTHING TO DO WITH EITHER THE SYSTEM OR
;	THE JOB SEARCH LIST).
;
;2)	JUNK DEVICES (E.G., MPX) ARE TOTALLY LOST, AS IS NUL:
;
;3)	"USER-IMPLEMENTED" DEVICES (E.G., DIRECT AND TMP:) ARE LOST.
;
;4)	.LKWLD MAY RETURN A HUMONGOUS NUMBER OF "FILES" FOR A VERY
;	SIMPLE FILE EXPRESSION ("TTY123: 'OR' TTY456:" WILL RETURN EVERY
;	PHYSICAL TTY IN THE SYSTEM). IT IS UP TO .CHKTM (AND RELATIVES)
;	TO SORT OUT WHICH FILES ARE JUNK, AND REJECT SAME. TRY IT WITH
