Full Transparency to Application Programs

Support for application programs is fully transparent to the user. No special exits, parameters or interfaces are required for SORT and other utilities. Unlike the SUBSYS implementation, PST does not require you to code DCB parameters in the JCL unless the application requires it without CA Compress. GDGs, tape processing, and concatenation of PST and uncompressed data sets are fully supported as long as the processing is sequential using QSAM or BSAM. CA Compress causes SORT, which ordinarily uses EXCP, to consider PST data sets to be SYSIN/SYSOUT or SUBSYS data sets and to process them using BSAM.
