# PROGRAM NAME- UPDATE PROGRAM
# PROGRAM WRITTEN BY- RHODE
# MOD NO.- 2
# MOD BY- KILROY TO ADD AGC CLOCK AND TE(V75E4ETTTTTE) UPDATE FEATURE.
# DATE- 01FEB67
# LOG SECTIONS- UPDATE PROGRAM PART 1 OF 2
# UPDATE PROGRAM PART 2 OF 2
# ASSEMBLY- REV 93 OF SUNBURST
# FUNCTIONAL DESCRIPTION- TO PROCESS COMMANDS AND DATA INSERTIONS
# REQUESTED BY THE GROUND VIA UPLINK.
# VERBS V64, V67, V70, V71, V72, V73, V75 AND V76 WILL NOT BE
# PROCESSED IF THE MISSION TIMERS ARE DISABLED(I.E. AN MP IS IN
# PROGRESS). OPERATOR ERROR LIGHT WILL BE TURNED ON.
# V65, V66 AND V74 WILL BE PROCESSED EVEN IF A MP IS IN PROGRESS
# CALLING SEQUENCE- TCF XXUPDAT WHERE XX = EXTENDED VERGS(64 TO 76)
# LST2FAN CONTAINS A LIST OF TCF XXUPDAT
# WHICH ARE USED BY VERBFAN IN PINBALL TO
# GIVE CONTROL TO THE UPDATE PROGRAM.
# SUBROUTINES CALLED- POSTJUMP,IBNKCALL, BANKCALL, CHECKMM, GRABWAIT,
# NEWMODEX, FREEDSP, WAITLIST, ENDOFJOB, NOVAC, TASKOVER, FINDVAC
# ENDUP, DOV67, DOV70, DOV71, DOV72, DOV73, DOV74, DFITMCAL,
# GRRPLACE, NVSBWAIT, ENDIDLE, XACTALM, MGETUP, UPDATINT, TPAGREE
# NORMAL EXIT MODE- TC BANKCALL
# CADR ENDUP
# ALARM OR ABORT EXIT MODE- BZF XACTALM IF MP IN PROGRESS
#
# TC BANKCALL IF MP IN PROGRESS
# CADR XACTALM
# RESTART PROTECTION- NONE FOR VERBS 64 TO 74. RESTART PROTECTION IS
# INCLUDED FOR V75 AND V76 UNDER THE FOLLOWING CIRCUMSTANCES-----
# 1. THE DATA HAS BEEN SENT AND VERIFIED(I.E. V33E HAS BEEN SENT)
# 2. PROGRAM IS IN THE PROCESS OF MOVING DATA FROM STBUFF TO
# APPROPRIATE REGISTERS OR
# VERB 75 OR VERB 75(INDEX = 4 ONLY) PROGRAM(S) ARE WAITING(VIA WAITLIST
# 3 SEC CALL) FOR ORBITAL INTEGRATION TO BE TURNED OFF.
# ***OF COURSE ALL GROUND UPDATES(IF LOST DUE TO A RESTART) CAN
# BE RESTARTED BY SENDING THE COMMANDS AND DATA A SECOND TIME***
