;THIS MODULE HAS BEEN DEVELOPED TO AID IN THE CONVERSION OF BATCON AND LPTSPL,
; AND IN THE DEVELOPMENT OF SPROUT-10. ALTHOUGH THIS MODULE PERFORMS THE
; FUNCTIONS REQUIRED BY THOSE PROGRAMS, IT IS NOT INTENDED TO BE
; A COMPLETELY GENERAL IPCF OR PROGRAM-QUASAR INTERFACE.
;AC USAGE IN THIS MODULE
; ALL ROUTINES MAY DESTROY S1, S2, & TEMP AS WELL AS ANY AC'S
; EXPECTED TO CONTAIN ARGUMENTS (T1, T2, ...)
;EXCEPTION: INITIALIZATION (CSPINI) HAS FULL USE OF ALL THE REGISTERS
SUBTTL CSPINI -- CUSP Initialization
;CSPINI SHOULD BE CALLED BY THE CUSP UPON PROGRAM INITIALIZATION.
;IF AT THE CALL, S1 = 0, THEN CSPQSR WILL HANDLE THE INTERRUPT SYSTEM
; IF S1 = -1, THEN THE CALLER WILL TAKE THE RESPONSIBILITY
;RETURNS S1 = THE PID ACQUIRED FOR THE CALLER
; S2 = THE ADDRESS OF THE IPCF INTERRUPT FLAG (AN INTERRESTING LOCATION)
