SUBTTL Edit history

;Edit	Who	What
;----	---	----
;
;  2     JJF	Add support for SHOW PENDING CONNECTS and
;		SHOW HOST-INITIATED-CONNECTS commands.  Incorporate
;		KDO's fix for SHOW SESSIONS.  Fix output of SHOW SESSIONS
;		to be more Galaxy-like.
;
;  3	 JJF	Fix bug that caused LCPORN to blow ORION out of the water with
;		an invalid message type. GCO 10556.
;
;  4	KDO	Fix the length of the argument list.  GCO 10574.
;
;  5	RBW	Add "Port Name" Columns to the SHOW SESSIONS Display.  Add
;		other changes to make LCP compatible with TOPS-20.  Fix
;		minor bugs in SHOW HOST-INITIATED and SHOW PENDING commands.
;
;  6	RBW	Move Version Number code to LCPTAB to keep TOPS-20 OPR
;		happy.  MAKE SURE VERSION NUMBERS GET UPDATED THERE!!
;
;  7	RBW	Fix bug in SHOW PENDING-REQUESTS.  If there are Reverse LAT
;		connects, but none are pending, say so!
;
; 10	JJF	Fix problems which caused SHOW SESSIONS and both flavors
;		of SHOW HOST-INITIATED-CONNECTS to make ORION croak.
;		1. Remove all use of Preserved ACs except P1 from both
;		routines.
;		2. Make sure that we re-call SHWPCS to get the status
;		of the connect after doing a $TEXT.  TF no longer has the
;		valid status in it.
;		22-Apr-88 GCO:10623 QAR:T10L342:00033
;
; 11	GAS 	Update copyright notice
;
; 12	RBW/JJF	Fix problem with SET SERVICE-NAME accepting names with
;		spaces in them -- remove space from the break mask of 
;		acceptable characters.
;		1-Jun-88 GCO:10635
;
; 13	JJF	Solve problem where LCP will get an ILM stopcode on the
;		KS under TOPS-10.  Insert code to see if the system
;		has LAT support.  If it doesn't, reject all LAT functions.
;		12-Oct-88 GCO:10659 SPR:10-36169
;
; 14	KDO	Modify the SHOW CHARACTERISTICS display to display
;		twenty characters worth of service name instead of six.
;		26-Oct-89 GCO:10679 SPR:10-36281
