CA Dynam for VSE User Guide

Deleting Files
DA Files
No truncation is performed on DA files because no EOF record is written.
Deleting Files
This section describes how to delete data and work files.
Deleting Data Files
You can specify in the JCL that a sequential disk (SD), direct access (DA) or
ISAM file is to be deleted when closed. The JCL entry overrides the default
option (no deletion). To request deletion, specify either of these DLBL option
codes:
Option code D
Option code X
DELETE at input CLOSE
DELETE at input or output CLOSE
When deleting a file, the VTOC entry for that file is deleted—not the actual
data on the disk.
Deleting Work Files
A special case is encountered for IBM SORT work files. The IBM Sort/Merge
program does not close the SORTWK files. Therefore, CA Dynam/D will only
analyze the DLBL statements for the SORT work files when a SORTOUT
file name is closed. CA Dynam/D will then assume the D (delete) option.
If you do not specify the file name SORTOUT for the file used as the sort
output, you should include the option code W for that file; otherwise, the
SORTWK files will not be deleted. When a sort output file defined with option
code W is closed, CA Dynam/D will delete the SORTWK files used during the
job.
CA SORT Work Files
Sort work files used for CA SORT are always deleted if no longer needed.
