CA Dynam for VSE User Guide

Using CA Dynam/T
volseq
fileseq
gen
ver
Use this field to request a specific volume of a multivolume data set for input
files with a 1- to 4-digit number from 0 to 9999. Omit this field for output files.
The file sequence number field is not used by CA Dynam/T and should be
omitted in all cases. The multifile data set control provided by CA Dynam/T is
based upon the data set name and control records in the Catalog.
In this field, request a specific version of a data set for input files with a 1-to
4-digit version number from 0 to 9999. Omit this field for output files.
Use this field to specify option codes that control various processing functions.
Enter a 1- to 2-digit number, 0—99.
G=nnnnn or GEN=nnnnn
Use the field to specify an absolute generation number from 1 to 65535 for the
data set. This number lets you always access this particular version of the data
set. This is a positional entry and must be coded after all other parameters. If
the first option is a keyword and IBM options are omitted, at least 1 comma
after file-id is required; otherwise, at least 2 commas are needed.
Example:
// TLBL filename,'file-id',,G=123.
Retention
The value specified in the TLBL date field overrides the number of retention
days specified in the Catalog only if it is the larger of the two. It applies only to
the version created using that TLBL.
Examples:
// TLBL FILENAME,'FILE-ID',10 (number of retention days)
// TLBL FILENAME,'FILE-ID',2099/365 (expiration date in Julian format)
Version (Generation)
Specification
CA Dynam/T defaults to the current version of the data set requested for
input files. You can select another version three ways.
If the length of the data set name is as follows:
• Does not exceed 59 characters, including the generation specification,
append the relative generation number to the data set name as part of the
file ID field. Place the number within parentheses after the period which
follows the data set name. Indicate a generation by specifying the number
of generations prior to the current generation with a minus sign before the
number.
