Data set naming conventions

Some IDF commands cause data to be written to or read from files. Since IDF was originally written to run on CMS, the commands are oriented towards the naming conventions used by the CMS file system.

The mapping of the CMS file conventions to z/OS is:

CMS: Equivalent on z/OS
fn: PDS member name (ignored if using sequential file)
ft: DDNAME, which in turn points to the z/OS data set name
fm: Not used on z/OS

Note: You must allocate the DDs using TSO ALLOC commands, or place them in your TSO startup procedure JCL, or place them in the batch IDF JCL. No dynamic allocation is performed.
