;THE COMMON SUBPROGRAM CONSISTS OF 6 FILES ASSEMBLED TOGETHER AS ONE SUBPROGRAM
1. F.MAC -- FEATURE TESTS (OUTPUT OF MONGEN).
2. S.MAC - THE USUAL SYSTEM SYMBOL DEFINITIONS ASSEMBLED WITH
EVERY MONITOR SUBPROGRAM
3. HDWCNF.MAC -- HARDWARE CONFIGURATION
4. TTYCNF.MAC -- TERMINAL CONFIGURATION
5. REMCNF.MAC -- REMOTE CONFIGURATION
6. COMMON.MAC - THE REST OF THIS PROGRAM WHICH IS THE SAME SOURCE FOR
ALL CONFIGURATIONS. HOWEVER, THE ASSEMBLIES ARE CONDITIONED BY
SYMBOLS AND MACROS DEFINED IN 2.
THE FOLLOWING SYMBOLS AND TABLES ARE GENERATED BELOW:
A. MONITOR STARTUP LOCATIONS (400-407), HENCE LOAD THIS FIRST.
B. JOB TABLES - LENGTH DEPENDENT ON MAXIMUM NUMBER OF JOBS ALLOWED
C. ALL VARIABLE STORAGE NOT ASSOCIATED WITH A PARTICULAR DEVICE
D. COMMON SUBROUTETURNS
E. COMMON BYTE POINTERS
F. TABLE OF SERVICE ROUTINE INTERRUPT LOCS TO BE LINKED BY ONCE ONLY CODE
G. TABLE OF DEVICE DATA BLOCK ADDRESSES AND NUMBER TO BE USED BY ONCE TO
LINK THEM TOGETHER AND GENERATE MULTIPLE COPIES.
H. ASSIGNMENT OF PI CHANNELS
I. PI CHANNEL SAVE AND RESTORE ROUTINES
J. UUO TRAP LOCATIONS 40/41, 60/61
K. APR INTERRUPT LOCATIONS CPU0,1, KA10/KI10
L. SYSTEM CRASH STOP CONI'S.
NOTE: SEE COMDEV FOR DEVICE DEPENDENT CODE, DATA, AND SYMBOLS
LEVEL D DISK SERVICE PARAMETERS:
ALL SYMBOLS ANAS ONATIONS ARE IN A SEPARATE FILE CALLED
COMMOD.MAC WHICH IS ALSO ASSEMBLED WITH S AND CONFIG (BUT NOT WITH FEATURS FILES).
THE SEPARATE FILE IS FOR TWO REASONS:
1. ANTICIPATING MULTIPROCESSING SYSTEMS WHICH SHARE DISKS AND 1 16K MEMORY
(THE DATA MUST BE IN THE COMMON MEMORY)
2. ELIMINATE THE NEED TO ASSEMBLE COMMOD IF NOT A DISK SYSTEM
(COMMOD.MAC TAKES LOTS OF CORE FOR ITS COMPLICATED MACROS)
THE FOLLOWING EQUATES ARE GENERATED FOR REMOTE
COMMUNICATIONS PROGRAM SETUP:
LOCSTA - THE STATION NUMBER OF THE (PDP10) CENTRAL SITE

REPEAT 0,<
;THIS SECTION CONVERTS NEW MONGEN SYMBOLS TO OLD MONGEN SYMBOLS
;SO THAT THE REST OF COMMON AND MONITOR CAN STILL USE THE OLD
;SYMBOLS. THIS WAS DONE RATHER THAN CONVERTING ALL OF THE
;MONITOR TO NEW SYMBOLS FOR TWO REASONS:
; 1. IT IS EASIER AND FASTER AND LESS LIKELY TO INTRODUCE BUGS, AND
; 2. IT ALLOWS CUSTOMERS TO USE OLD MONGEN WITH A MINIMUM
;OF TROUBLE: ONLY A FEW EXTRA SYMBOLS MUST BE DEFINED.
;THE MONITOR WILL PROBABLY BE CONVERTED TO THE NEW MONGEN SYMBOLS
;AFTER THE 5.04 RELEASE. THE ORDER HERE PARALLELS THE OLD
;MONGEN ORDER.

SUBTTL CPU DATA BLOCK(S):
REPEAT 0,<
EACH CPU HAS ITS OWN DATA BLOCK, KNOWN AS A CDB.
IT IS USUALLY INDEXED BY AC P4, WHEN REFERENCED AT APR OR CLK INTERRUPT
LEVEL ROUTINES (SEE APRINT, CLOCK1, SCHED1, ERRCON MODULES).
THE REST OF THE MONITOR ONLY REFERENCES THE CDB FOR THE MASTER CPU.
IN THESE CASES IT WILL USUALLY USE THE OLD 6 CHAR NAME.
MANY LOCATION IN THE CDB PERTAIN ONLY TO THE MASTER CPU. HOWEVER,
FOR GENERALITY AND FUTURE EXPANSION TO A MASTER/MASTER SYSTEM, INSTEAD
OF MASTER/SLAVE, THEY ARE INCLUDED IN CDB(WITH OLD NAMES
AND NO P4). A FEW LOCATIONS ARE REALLY SYSTEM PARAMETERS(EG CORTAL),
RATHER THAN CPU PARAMETERS. HOWEVER, THEY WERE IN THE MIDDLE OF A
GETTAB(NSWTBL) AND SO COULD NOT BE SEPARATED OUT WITHOUT INVALIDATING
SOME PROGRAMS.
RULE: ANY SYMBOL DIFINED AS .CP??? WILL ALWAYS INDEX BY P4. OLD
SYMBOLS AND .C0??? AND .C1??? SYMBOLS ARE NEVER INDEXED BY P4, SINCE
THEY ARE ABSOLUTE WITH RESPECT TO THE ORGIN OF THE MONITOR.
PRINCIPLE: THE FOLLOWING MACROS ONLY GENERATE INTERN SYMBOLS WHICH ARE
ACTUALLY USED. THIS MINIMIZES THE NO. OF SYMBOLS AND IS A USEFUL
DOCUMENTATION TOOL. IN OTHER WORDS A LOCATION WILL ONLY HAVE AN OLD
SYMBOL, OR A NEW .CP??? SYMBOLS, OR .CP??? AND .C0??? AS NEEDED.
FOR DEBUGGING WITH DDT, THE ABSOLUTE SYMBOLS FOR CPU0 AND CPU1 ARE
ALWAYS GENERATED AT LEAST AS LOCAL SYMBOLS.
>
REPEAT 0,<
PRINCIPLE: WHEN ADDING CONSTANTS OR VARIABLES TO COMMON,
GREAT CARE MUST BE EXERCISED IN DECIDING WHETHER TO PUT IT
IN THE CDB OR IN A SYSTEM DEPENDENT TABLE(.SYTBL).
IF THE CONTENTS COULD EVER BECOME CPU DEPENDENT IN THE FUTURE, BE
SURE TO PUT IT IN THE CDB INSTEAD OF .SYTBL. IF A MISTAKE IS MADE,
THE LOCATION WILL HAVE TO APPEAR IN THE CDBS AS WELL AS
.SYTBL IN ORDER TO INSURE COMPATIBLITY.
