COMMENT \
THIS CODE RESIDES IN A HIGH AREA OF USER CORE (CURRENTLY 700000).
IT IS LOADED FROM THE SSAVE FILE SYS:PA1050.EXE BY THE
MONITOR WHENEVER A FORK EXECUTES ITS FIRST 10/50 UUO (40-77, BUT NOT 0).
THE FIRST TIME, ENTRY IS VIA THE SECOND LOCATION OF THE ENTRY VECTOR.
THEREAFTER, 10/50 UUO'S RESULT IN AN IMMEDIATE TRANSFER TO
THIS CODE VIA THE FIRST LOCATION OF THE ENTRY VECTOR. WHEN
ANY 10/50 UUO IS EXECUTED, THE MONITOR MOVES LOCATION 40 TO
MONUUO (SPECIFIED BY FOURTH WORD OF ENTRY VECTOR), AND THE RETURN
PC TO MONUPC (SPECIFIED BY FIFTH WORD OF ENTRY VECTOR). THIS CODE
INTERPRETS THE UUO AND RETURNS DIRECTLY TO THE USER PROGRAM.
THIS CODE USES THREE OF THE RESERVED UUO'S (42-44) FOR INTERNAL
PURPOSES.
ASSEMBLY AND LOADING PROCEDURE:
@LOAD PAT
@START
@
THE START AFTER LOADING CAUSES THE CODE TO BE MOVED FROM ITS LOAD
LOCATION TO ITS RUNNING LOCATION IN HIGH CORE. THE SYMBOL
TABLE IS ALSO MOVED, AND THE POINTER ADJUSTED. AN SSAVE FILE
OF PAGES 700-777 SHOULD BE MADE TO BE USED FOR DEBUGGING.
TO PRODUCE THE SYSTEM FILE, START AT MAKEPF (MAKEPF$G). THIS WILL
WRITE A SSAVE FILE WITH WRITE PROTECTION INTO THE SPECIFIED FILE.
FOR DEBUGGING COMPATIBILITY PACKAGE, FIRST RESET, AND GET
THE TEN-50 PROGRAM TO BE USED FOR TESTING, IF ANY.
THEN, MERGE AN SSAVE FILE (WITH DDT AND SYMBOLS) OF THE
DEBUG VERSION OF PAT, TYPE DDT, THEN DEBUG$G TO SET UP THE
COMPATIBILITY VECTOR, PSI SYSTEM, AND TEMPORARY STORAGE.

REPEAT 0,<
TEMPORARY FILE STORAGE FOR JOB UUO.
THE "TMPCOR" UUO IS USED TO ENABLE A JOB TO LEAVE SEVERAL SHORT
FILES IN CORE FROM THE RUNNING OF ONE USER PROGRAM OR CUSP TO THE
NEXT. THESE FILES MAY BE REFERRED TO BY A THREE CHARACTER FILE NAME,
AND ARE UNIQUE TO EACH JOB, I.E. A JOB CAN ONLY REFERENCE ITS OWN
FILES. ALL FILES ARE ALWAYS DELETED WHEN A JOB IS KILLED.
EACH FILE APPEARS TO THE USER AS ONE DUMP MODE BUFFER. THE ACTUAL SIZE OF A
TEMPORARY FILE, THE NUMBER OF TEMPORARY FILES A USER CAN HAVE,
AND THE TOTAL CORE SPACE A USER CAN TIE UP ARE PARAMETERS DETER-
MINED AT MONGEN TIME. ALL TEMPARARY FILES RESIDE IN A FIXED AREA
IN THE MONITOR, BUT THE SPACE IS DYNAMICALLY ALLOCATED AMOUNG
DIFFERENT JOBS AND THE SEVERAL DIFFERENT FILES OF ANY GIVEN JOB.
THE PRIMARY PURPOSE OF THE TEMPORARY STORAGE SYSTEM IS FOR SHORT
CONTROL FILES, E.G. CCL FILES, TO LIVE IN CORE, THEREBY SPEEDING
UP RESPONSE TIMES AND REDUCING DISK OPERATIONS. ACCORDINGLY,
SHOULD A PROGRAM ATTEMPT TO WRITE A FILE WHEN THERE IS
INSUFFICIENT SPACE, EITHER IN THE ENTIRE BUFFER AREA OR BECAUSE
THE USER HAS EXCEEDED HIS QUOTA, THE UUO GIVES AN ERROR RETURN.
THE CUSP CAN THEN WRITE THE DATA AS A SHORT DISK FILE.
SIMILARLY, SHOULD A PROGRAM FAIL TO FIND A FILE UPON READING IT,
IT WILL GET AN ERROR RETURN AND CAN THEN LOOKUP A SHORT DISK FILE.
IT IS VERY IMPORTANT TO REALIZE THE TEMPORARY NATURE OF THESE
FILES. FOR EXAMPLE, UPON WRITING, THE OLD FILE IS DELETED BEFORE
CHECKING FOR SPACE FOR A NEW VERSION. THE OLD FILE COULD BE LOST WITHOUT
A NEW ONE REPLACING IT. ALSO, THERE CAN BE NO GUARANTEE THAT FILES
WILL FIT IN CORE.
THE TMPCOR UUO IS NOT INTENDED TO REPLACE A FUTURE, MORE
GENERAL, DEVICE INDEPENDENT SERVICE ROUTINE FOR "CORE". HOWEVER,
THE SPACE TAKEN UP BY DEVICE DATA BLOCKS, ETC., IN THAT MORE
GENERAL ROUTINE WOULD REPRESENT UNNECESSARY OVERHEAD FOR EXTREMELY
SHORT DATA, SUCH AS CCL COMMAND FILES.

C(AC) MUST ALWAYS BE SET UP BY THE USER PROGRAM PRIOR TO EXECUTING

REPEAT 0,<
CODE-0 -- GET FREE SPACE
THE IS THE ONLY FORM OF THE TEMP UUO THAT DOES NOT USE A TWO
WORD PARAMETER BLOCK. C(AC) WOULD ORDINARLY BE SET TO ZERO FOR THE
GET FREE SPACE UUO. THE USER PROGRAM ALWAYS GETS A NORMAL RETURN
(UNLESS THE SYSTEM DOES NOT HAVE THE TEMP UUO). C(AC) IS SET TO
THE NUMBER OF WORDS OF FREE SPACE AVAILABLE TO THE USER.
CODE=1 -- READ FILE
IF THE SPECIFIED FILE NAME IS NOT FOUND, C(AC) IS SET TO THE
NUMBER OF FREE WORDS OF SPACE AVIALABLE FOR TEMP FILES, AND THE
ERROR RETURN IS TAKEN.
IF THE FILE IS FOUND, C(AC) IS SET TO THE LENGTH OF THE
FILE IN WORDS, AND AS MUCH OF THE FILE AS WILL FIT IS COPIED INTO
THE USERS BUFFER. THE USER CAN CHECK FOR TRUNCATION BY COMPARING
C(AC) WITH BUFLEN UPON SUCCESSFUL RETURN FROM THE TEMP UUO.
CODE=2 -- READ AND DELETE FILE
THIS IS THE SAME AS CODE=1, EXCEPT THAT IF A FILE WAS FOUND
IT IS ALSO DELETED AND ITS SPACE RECLAIMED.
>
REPEAT 0,<
CODE=3 -- WRITE FILE
IF THERE IS ALREADY A FILE OF THE SPECIFIED NAME, IT IS
DELETED AND ITS SPACE IS RECLAIMED.
THE REQUESTED SIZE OF THE FILE IS SPECIFIED BY BUFLEN.
IF THERE IS NOT ENOUGH SPACE TO WRITE THE ENTIRE FILE, NOTHING
IS WRITTEN, C(AC) IS SET TO THE NUMBER OF FREE WORDS OF SPACE
AVAILABLE TO THE USER, AND THE ERROR RETURN IS TAKEN.
IF THERE IS ENOUGH SPACE, THE FILE IS WRITTEN. C(AC) IS SET TO
THE AMOUNT OF SPACE LEFT AFTER THE FILE HAS BEEN WRITTEN AND THE
NORMAL RETURN IS TAKEN. FILES ARE ALWAYS FILLED UP WITH ZEROS TO THE
NEXT EVEN MULTIPLE OF THE BLOCK LENGTH (TMPBL).
THIS EVEN LENGTH IS READ BACK IN.
CODE=4 -- READ DIRECTORY
THE ERROR RETURN IS NEVER TAKEN.
C(AC) IS SET TO THE NUMBER OF DIFFERENT FILES IN THE JOB'S
TEMPORARY FILE AREA. IN ADDITION, AN ENTRY IS MADE FOR EACH FILE
IN THE USER BUFFER AREA UNTIL THERE IS NO MORE SPACE OR ALL FILES HAVE
BEEN LISTED. THE USER PROGRAM CAN CHECK FOR TRUNCATION BY COMPARING
C(AC) UPON RETURN WITH BUFLEN.
DIRECTORY ENTRY FORMAT
XWD NAME,SIZE ;NAME=FILE NAME, SIZE =FILE LENGTH IN WORDS.
CODE=5 -- READ AND CLEAR DIRECTORY
THIS IS THE SAME AS CODE=4 EXCEPT THAT ANY FILES IN THE JOB'S
TEMPORARY STORAGE AREA ARE ALSO DELETED AND THEIR SPACE RECLAIMED.
THIS UUO IS EXECUTED BY THE LOGOUT CUSP.
