Discussion

The DD_NAME subroutine enables you to find out how many definitions of a given definition type exist, and then ask for a list of their names. There are two ways to call DD_NAME:

• DDN_COUNT enables you to retrieve the count for a definition type.
• DDN_LIST enables you to retrieve a list of definition names.

DDN_COUNT

If you pass DDN_COUNT, the DD_NAME subroutine returns the number of definitions that exist for the specified type.

DDN_LIST

If you pass DDN_LIST, DD_NAME returns an array of definition names for the requested type. You can retrieve as many names as you want, and you can specify the name at which to start. These names are returned in alphabetical order, starting with either the first name found or the specified name. DD_NAME returns as many names as are found or as are requested, whichever is smaller. The actual number of names in the array can be returned in #names.

You must make sure that the buffer passed is large enough to hold the number of names that you are requesting.
