Operation
CONTROL ENTERS DMSDLK AT THE DLKINL CSECT. THE COMMAND LINE IS SCANNED FOR ERRORS AND ADCONS ARE RELOCATED. THEN SYSRES IS LOCATED AND, IF THE DISK OPTION IS DESIRED, THE OLD MAP FILE IS ERASED IF IT EXISTS AND A NEW ONE CREATED. A CHECK IS MADE TO SEE IF OLD TEMPORARY FILES WITH A FILENAME OF 'FN' ARE PRESENT AND, IF SO, TO ERASE THEM. THE PRIVATE RELOCATABLE LIBRARY, IF SPECIFIED, IS LOCATED AND ADDRESSES ARE CALCULATED. DOSLIB IS THEN FILEDEFED AND OPENED. A CHECK IS MADE FOR DOSLNK AND, IF NOT AVAILABLE, A DUMMY INCLUDE CARD IS SET UP AND CONTROL PASSES TO NORMAL PROCESSING. IF DOSLNK IS AVAILABLE, THE FILE IS READ AND ACTION CARDS ARE PROCESSED. WHEN THE FIRST NON-ACTION CARD IS LOCATED, THE OPTIONS SPECIFIED ON THE ACTION CARDS (IF ANY) ARE PROCESSED AND CONTROL PASSES TO NORMAL PROCESSING. WHEN THE CSECT HAS COMPLETED ITS PROCESSING, IT WILL BE OVERLAID WITH WORK TABLES AND BUFFER AREAS BY SUBSEQUENT PROCESSING. PHASES FORMED FROM LANGUAGE TRANSLATOR RELOCATABLE MODULES ARE ASSIGNED AREAS OF MAIN STORAGE. WHEN ACTION REL IS SPECIFIED OR DEFAULT AND ACCEPTED FOR A PHASE, A RELOCATABLE PHASE WILL RESULT. WHEN ACTION NOREL IS SPECIFIED OR DEFAULT OR ACTION REL NOT ACCEPTED FOR A PHASE THE RESULTING PHASE WILL BE NOT RELOCATABLE. THE FOLLOWING CONTROL CARDS ARE PROCESSED DURING NORMAL PROCESSING: PHASE - AS EACH PHASE IS BUILT, THE INFORMATION FOR THE PHASE IS SET UP IN CPHENT. THE NAME IS CHECKED FOR DUPLICATES AND THE ORIGIN IS DETERMINED. IF THIS IS NOT THE FIRST PHASE THE PREVIOUS PHASE IS INSERTED IN THE CONTROL DICTIONARY TABLE AND THE NUMBER OF BLOCKS ON SYSUT2 CONTAINING BOTH TEXT AND RLD INFORMATION ARE DETERMINED. IF THE PHASE IS RELOCATABLE, A SWITCH IS SET AND PASS 3 OF RLD RECORDS IS INDICATED. INCLUDE - IF AN UNNAMED SUB-MODULE, CARD IS IGNORED. OTHERWISE, THE NAME IS COMPARED AGAINST THE PRIVATE RELOCATABLE DIRECTORY, CMS TEXT FILES AND SYSTEM RELOCATABLE DIRECTORY. IF NOT FOUND AN ERROR MESSAGE IS ISSUED AND PROCESSING CONTINUES. IF FOUND, THE PREVIOUS FILE'S ADDRESSES ARE STORED AND THE NEW FILE IS READ AND PROCESSED. WHEN AN END CARD IS READ THE PREVIOUS FILE'S ADDRESSES ARE RESTORED AND ITS PROCESSING CONTINUES. ENTRY - IF NOAUTO HAS NOT BEEN SET EXTERNAL REFERENCES, IF ANY, ARE RESOLVED, IF POSSIBLE, BY AUTOLINKING THE REQUIRED MODULES INTO THE PHASE. CONTROL IS THEN PASSED TO END PROCESSING. THE TRANSFER ADDRESS, IF SPECIFIED, IS OBTAINED AND THE NUMBER OF TEXT BLOCKS AND RLD BLOCKS IS CALCULATED. IF NOMAP WAS NO SPECIFIED, THE MAP IS PRINTED, TYPED, OR WRITTEN ONTO DISK AS SPECIFIED BY THE OPTION LIST OF THE COMMAND LINE. THE RLD RECORDS ARE THEN PROCESSED AND WRITTEN ONTO SYSUT2. THE STOW TABLE ENTRY IS THEN COMPUTED AND WRITTEN ONTO DOSLIB AS THE FIRST RECORD. THEN SYSUT2 IS READ AND WRITTEN ONTO DOSLIB IN 1024 BYTE BLOCKS WITH THE EXCEPTION OF THE LAST RECORD, WHICH CAN BE ANY LENGTH. A STOW IS THEN ISSUED TO INSERT THE NAME OF THE PHASE IN THE DIRECTORY. THE SYSUT1 AND SYSUT2 FILES ARE THEN ERASED, DOSLNK AND DOSLIB FILES ARE CLOSED, AND CONTROL RETURNS TO CMS.
