Changes since the last edition of the manual

The manual “DMS Macros” was last published for BS2000 OSD/BC V10.0. The following major changes have been made since the last edition of the manual:

Changes to the macro interfaces

Macro / Operand or RC	Nature of the change
CATAL	New operand: NETCCS defines NET-CODED-CHAR-SET.
	New operand from V11.0B onwards: NUM_OF_BACKUP_VERS determines, if and how many versions of a file can be saved in an version backup archive.
FCB	New operand: LBP_REQUIRED requests last-byte pointer (LBP) processing
	New operand: SAM_NODE_FILE_ENABLE allows SAM node file processing
	New operand: UPAM_RAW_ACCESS enables UPAM RAW access to SAM node files
FSTAT	New operand: LBPOINT for file selection, depending on the value of the last-byte pointers value. The output area also contains the NETCCS file attribute.
	New operand from V11.0B onwards: VERSION-BACKUP for selecting files based on whether they can be part of an version backup. A file can only be part of an version backup if the NUM-OF-BACKUP-VERS file attribute has a value > 0. The output area also includes the NUM-OF-BACKUP-VERS file attribute.
IMPNFIL	New operand value: FILESTR=*SAM imports node files as SAM file

Fundamental information on the use of Net-Storage in BS2000 is provided in the “Introduction to System Administration” [7]. How to work with BS2000 files and node files on Net-Storage is described in the “Introductory Guide to DMS” [1].

The device and volume type tables are contained in the "System Installation" manual [16]. Information on the volume types of DMS (Net-Storage and tape processing is provided in the “Commands” manual [3].

General change

GS (global storage) as a non-volatile cache medium is no longer supported.

From BS2000 OSD/BC V11.0 onwards, the connection of peripheral devices is only supported via type FC channel. Together with the ESCON connection, the function “shareable private disk” (SPD) has been omitted.
