CA Dynam for VSE User Guide

Defining File ID Option Codes
IE
ISAM extend
Indicate ISE DLBL function for catalog-controlled files.
JX
Causes a controlled file to be deleted at end of job after the file is processed.
If JX is specified for an input file and the job step abnormally terminates, the
file is not deleted and the job can be rerun.
K
Keep SD file
The K option causes the sequential disk file to be kept after closing the file,
even when the user program indicates deletion of the file. The K option, if
specified for sort work files, prevents CA Dynam/D from deleting the file. The
purpose of this option is to override any specification to delete a file.
L
Locked file
Data set is locked for read-only usage. If L is not specified, then the file will
not be locked. The L option applies to both CA Dynam/D-controlled and
noncontrolled files.
M
Messages to SYSLOG
Indicates that informative messages produced by CA Dynam/D are to be
directed to SYSLOG. Note that, if informative messages are not requested at
the time CA Dynam/D is installed, then the option code M must be specified in
order to obtain these messages on SYSLOG.
N
No truncate at CLOSE
Inhibits truncation of SD files at CLOSE time. Overrides the default option of
automatic truncation of SD files. The truncation facility applies only to CA
Dynam/D-controlled files.
NA
No automatic secondary allocation
Prevents automatic secondary allocation for this file. Unnecessary if more than
one allocation is already defined.
NF
No fragmentation
The NF option code unconditionally prevents fragmentation or minimum
percentage space allocation for the file.
