ABSTRACT: THIS PROGRAM FUNCTIONIZE AS A DRIVER FOR IBM
3740 SERIES DISCETTE. WITH AUTOMATIC CHECK
OF LABEL, BAD TRACK AND DATASETFILE.
SIZE: 4676 BYTES. INCLUDING TWO 512 BYTES INPUT BUFFERS.
DATE: MARTS 16.TH 76.
MODES: OPEN(IN,OPERATION ) JUST FOR TRANSFERING DATASET TO MODULE.
OPERATION:=1 FOR READ 3 FOR WRITE.
PARAMETERS FOR OPEN FOR DATASET(S) MUST BE MADE
IN AN CONVERSION STRING CONNECTED TO
THE FILE DESCRIPTION.
TO SENSE STATUS FOR DEVICE WITHOUT TESTING CONTENT
OF DISKETTE SET FD.ZONV TO ZERO AND MAKE AN OPEN.
EXAMPLE: FDZONV:=FD.ZONV; FD.ZCONV:=0; OPEN(FD,READ);
COULD BE USED IF READING SHOULD BE DONE AUTOMATICALLY.
COMMAND:
MODE: STRING(1) FROM 1 , READ=R WRITE=W
DUMMY YET.
UNIT: STRING(1) FROM 2 ASCII VALUE OF UNIT.
ACCEPT: STRING(1) FROM 3 IF SEQUENCE ERROR WAS
MET AND READING IS WANTED ANYWAY THEN
VALUE DIFFERENT FROM SPACE SHOULD BE
INSERTED.
VOLID: STRING(6) FROM 4 VOLUME LABEL.
DATASET: STRING(8) FROM 10 DATASETNAME.
NOTE THAT IF VOLID = SPACES THEN NO CHECK OF
LABEL WILL BE DONE.
THAT IF DATASETNAME = SPACES THEN ALL LEGAL
DATASET WILL BE TRANSFERRED UNTIL A DDR1 MARK
IS MET.
STATUS:
B1: OFF-LINE.
B5: SEQUENCE ERROR.
B6: DISCETTE CONTAINS ILLEGAL INFORMAITION.
B7: DATASET REACHED EOD.
B8: BLOCK LENGTH ERROR.
B11: DISCETTE FULL / OR END MEDIUM IF DATASET IS
CONCECUTIVE.
B12: POSITION ERROR.
B14: FATAL SYSTEM ERROR. DISC CANNOT BE READ.

OUTPUT MESSAGES:
VOLUME LABEL MISSING VOLUME LABEL SECTOR NOT FOUND
OR VOLUME ID ILLEGAL
HEADER LABEL MISSING HEADER LABEL SECTOR NOT FOUND
DATASET NAME MISSING THE TRANSFERRED DATASET NAME IS
IS NOT FOUND BETWEEN SECTOR 8 AND 26
FILE STARTS IN TRACK 0 THE DATASET IS PLACED ILLEGAL ON DISCETTE
FILE ENDS ILLEGAL THE DATASET IS PLACED ILLEGAL ON DISCETTE
RECORD LENGTH ERROR THE RECORD IS GREATER THAN 512
OR BETWEEN 128 AND 512
OR LESS THAN 1 CHARACTERS
SEQUENCE ERROR THE SEQUENCE ARE NOT CONSECUTIVE
DEVICE RESERVED ANOTHER PROGRAM USING FD DRIVER.
FD DRIVER MISSING FD DRIVER NOT IN CORE.
AFTER ERROR THE LABEL WILL BE DISPLAYED ON THE CONSOLE
******** NOTE *********
IF "PARITY ERROR" OR "POSITION ERROR" OR "TIMEOUT" OCCURS ON SCREEN
THEN IT MEANS THAT THE DICETTE WAS IMPOSSIBLE TO
READ. CONTACT RC AND GIVE A LOG WITH IF POSSIBLE.
AFTER THESE ERRORS : RECORD NR: XXXX OCCURS WHICH MEANS
THAT THE SECTOR WITH NUMBER 1 <= SECTOR <= 2002 WAS
DEFECT.
**** NOTICE ****
SPECIAL VERSION USING 512 BYTES BUFFERS
USED TOGETHER WITH SPECIAL P&T PROGRAMS P1051 AND P1052.
THIS VERSION SHOULD NOT BE USED ANYWHERE ELSE.

AUTHOR: DATE: CHANGE:
CAMS 76.01.13 EOD IS ALLOWED TO BE 1 > EOE
CAMS 76.02.17 CORRECT MODULE TO MANAGE IBM
ERMAP FORMAT.
CAMS 76.03.16 CHANGE MODULE TO BE USED
MORE GENEREL. (SLAKTERIFORBUNDET).
CAMS 76.05.20 MODIFIE DELETED RECORDS
CAMS 77.12.13 ALLOWED EMPTY DATASET.
JSVJ 78.09.25 POSITIONING IMPLEMENTED.
PBP 78.11.30 MODIFIED FOR 3751 DRIVER.
OPEN STATEMENTS ARE RE-
PLACED BY TRANSFER
STATEMENTS. THIS MAKES
IT POSIBLE TO USE
MORE THAN ONE UNIT
AT THE SAME TIME.
