List and log data sets

ISPF helps you get hardcopy listings of source modules, and maintains a log of significant user activities. These items are kept in data sets called the list data set and the log data set, respectively.

When needed, the two data sets are allocated automatically. They are temporary data sets named:

prefix.userid.SPFn.LIST
prefix.userid.SPFLOGn.LIST

Note: The data set name used can be modified under the operation of site-defined options. See the section "Temporary data set names" in ISPF Planning and Customizing Guide.

prefix: The data set prefix in your TSO profile. Used only if it is different from your user ID.
userid: Your user ID.
n: A number from 0 to 9.

If you have specified in your TSO profile a data set prefix that differs from your user ID, the data set names begin with your data set prefix, followed by your user ID. Once generated, these data sets remain open throughout your ISPF session. However, even though they are open, you can still process them by using the ISPF LIST and LOG commands.
