CA Dynam for VSE User Guide

Using CA Dynam/T
Recording Density (MODE) Specification
CA Dynam/T enables you to decide the recording density (or mode) of a data
set. You can indicate tape density in the following ways:
• As a TLBL option in the file-ID field
• In the Catalog as a data set attribute
The TLBL specification overrides a Catalog specification for the data set.
In TLBL Statements
Although recording density is actually a characteristic of a data set rather than
of a particular job stream, you can specify recording density on the TLBL in the
file-ID field. Place an alphanumeric CA Dynam/T option code in the file-ID
field—no numeric option codes exist for recording density. These are the
permitted file-ID option codes:
30 1600 BPI Streaming: high speed and short gap (8809 only)
50 1600 BPI Start-Stop: low speed and long gap (8809 only)
60 1600 BPI Start-Stop: low speed and short gap (8809 only)
90 1600 BPI Streaming: high speed and long gap (8809 only)
