List data sets

In the List ID field, you can enter the name you want ISPF to use to identify the list data set that will contain the foreground processor output. This name is passed to the foreground processor by either the LIST or PRINT option. These rules apply:

If the input data set is partitioned the List ID field is optional:
- Leave the List ID field blank if you want ISPF to use the input member name to identify the output list data set.
- Enter a LIST ID if you want to use a name other than the input member name to identify the output list data set.
If the input data set is sequential, you must enter a LIST ID.

For best results, if you plan to debug your program later using COBOL interactive debug:

Enter the name of the member being compiled in the List ID field if the input data set is partitioned.
If the input data set is sequential, enter the name of the sequential data set.

Then, when you debug your program, use these same names in the PROG ID fields on the COBOL Interactive Debug panel.

ISPF names the listing:

prefix.userid.listid.LIST

where

prefix

is the data set prefix in your TSO profile, if you have one and if it is different from your user ID,

userid

is your user ID, and

listid

is the member name or the value in the List ID field.

If you are using the same list data set for multiple job steps, be aware that the DCB information can differ between the language processors and the linkage editor, causing an I/O error when trying to read the list data set. We suggest that you use a different list ID for each job step.
