Data set naming conventions
Certain 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/VSE® is:
- CMS
- Equivalent on z/VSE
- fn
- z/VSE librarian member name.
- ft
- DLBL name, which in turn points to the z/VSE data set name
- fm
- Not used on z/VSE
On z/VSE, you must reference files using DLBL statements (JCL), and libraries using LIBDEF statements.
