CA Dynam for VSE User Guide

Supported Program DTF Types
Dynamic file sorting sets up information to be sent to CA SRAM for sorting
files.
When a file's attributes are being modified, CA Dynam/FI replaces the user
program's DTF at OPEN with a new DTF in the partition GETVIS area. This file
type is compatible with the new file parameters defined at execution time. All
logical input/output requests are trapped and routed to the new DTF by CA
Dynam/FI.
Input file concatenation allows multiple input files to be read using one
OPEN/CLOSE.
