	ENTRY	SYSINI		;SYSTEM INITIALIZATION ROUTINE


;THE MONITOR MODULES SYSINI AND ONCE WERE COMBINED INTO ONE MODULE NAMED
;"SYSINI" IN THE VERSION 7.04 MONITOR.  THE AUTHORS OF THOSE MODULES WERE:
;ONCE	- T. HASTINGS/CHW/RCC/AF/DAL
;SYSINI	- TH/RCC/TL/AF/PH/DAL/BGE/RLD/JBS


;NOTE THAT SYSINI MAY INCLUDE INITIALIZATION ROUTINES WHICH SHOULD NOT
;BE CALLED. THIS HAPPENS IF THE FEATURE TEST SWITCH FOR A FEATURE IS ON,
;BUT THE MODULE IS NOT LOADED BECAUSE OF THE ANSWER TO A MONGEN QUESTION.
;TO SOLVE THIS PROBLEM, COMMON DEFINES SYMBOLS =0 IF THE ROUTINE IS
;NOT TO BE CALLED, = NON-0 IF IT IS TO BE CALLED.
