CA Dynam for VSE User Guide

Defining File ID Option Codes
SX
Causes a controlled file to be deleted at the end of a step after the file is
processed.
If SX is specified for an input file and the job step abnormally terminates, the
file is not deleted and the job can be rerun.
T
Truncate ISAM prime EXTENT or SD work file
The T option causes the ISAM (LOAD) prime EXTENT or SD work file to be
truncated. The T code is not a default option. This option applies only to CA
Dynam/D-controlled files.
W
Delete SORTWK files at CLOSE of this file
The W option is valid only on a DLBL statement and instructs CA Dynam/D to
delete currently open SORTWK files when the file containing the W option is
closed. (This option has no meaning for CA SORT users, because CA SORT's
work file is always deleted by CA Dynam/D.)
X
Delete file at input or output CLOSE
The X option causes a file to be deleted from the VTOC whenever it is closed
(for input or output).
Examples
The following examples illustrate the use of various CA Dynam/D option codes.
// JOB OPTION CODE EXAMPLE 1
* ALIGN OPTION CODE
// DLBL SDDOUT,'DISK.FILE (A,I)',2099/360
// EXTENT SYS006,POOL01,1,0,1,4
// EXEC PROGRAM
CADD002I ALLOCATED FILE=SDDOUT SYS006=201 SYSWK1 X=0/19/4
CADD022I RELEASED 3 TRACKS FILE=SDDOUT VOL=SYSWK1
// JOB OPTION CODE EXAMPLE 2
* DELETE OPTION CODE
* GENERATE FILE TO TEST DELETE
// DLBL SDDOUT,'DISK.FILE (D,I)',2099/360
// EXTENT SYS006,POOL01,1,0,1,8
// EXEC PROGRAM
CADD002I ALLOCATED FILE=SDDOUT SYS006=201 SYSWK1 X=0/3/8
CADD022I RELEASED 7 TRACKS FILE=SDDOUT VOL=SYSWK1
// JOB OPTION CODE EXAMPLE 3
