Activating and Deactivating BIM-EPIC Special Option Descriptions

Chapter 5. Activating and Deactivating BIM-EPIC 5-43

YES should not be used unless 3490’s are the only tape cartridge drives being used and

they are all the same type, i.e., all 3490 or all 3490-E . If it is specified in mixed cartridge

environments (3480, 3490, 3490-E), the results are unpredictable.

If YES is specified and a tape-occupied cartridge cuu is owned at EOJ time, the cartridge will

be rewound but not unloaded. ERD ownership will be released.

If YES is specified: When auto-cataloging a CATRT1 file EPIC will set the secondary extent

allocation to be the same as the primary extent allocation, instead of half of the primary

allocation

If ALTMSGS=NO, EPS099=YES will emit the ALTMSG format for EP005 and EPS033

messages. This setting can be useful if a console manager truncates the last few characters of

the "normally” formatted” message

This EPS is intended for use with COBOL/VSE and other LE/VSE-conforming program

products (PL/I, C, and HLASM).

When programs created with these compilers cancel, the LE will close all open files before

terminating the program. This is done to comply with ANSI standards and is a change from

previous compilers such as COBOL F.

The BIM-EPIC catalog entries for any output files that were closed in this manner will be

treated as "Version 1". There is no indication a cancellation has occurred and the probably

invalid tape or disk data can be inadvertently used as input to follow-on programs.

When a cancellation occurs in a non-LE program, the files are not closed, and their BIM-EPIC

catalog entries show as "OPEN" instead of "Version 1". This prevents them from being used

as input to follow-on jobs.

EPS100=NO, the default, does not alter the above description.

EPS100=YES causes the BIM-EPIC catalog entry to be shown as "OPEN", thereby

preventing the inadvertent use of the data. The files will still have been closed, however, so

VSE EOF indicators will be present on the tape or disk dataset.

EPS100 does not apply to "Start Track 1" disk datasets. This is because they do not have

entries in the BIM-EPIC catalog. These files will have the proper VSE EOF indicators and are

available for use by follow-on jobs.

It also does not apply to any BIM-EPIC controlled datasets in a CICS partition (usually,

there are no-BIM-EPIC controlled files in CICS partitions).
