Documentation
The LA utility is a one-line CLIST which invokes the PDS utility to access its formatted LISTALC table display. As you may or may not know, the TSO LISTALC (or LISTA) command will show you what datasets are currently allocated to which DDNAMEs in your TSO session. It is helpful information, but not in a very useful format. The PDS utility has a builtin function which displays these allocations in a scrollable table and permits you to process against the datasets in a variety of ways. The PDS utility can only be invoked with a dataset name to process against, so the LA utility uses your ISPF profile dataset as the "seed dataset" if you will. The help provided with this function in PDS is fairly good so you can use it to further familiarize yourself with the LISTA screen functions. Note: since you are in PDS, you will have to "END" twice to exit this utility table display....just the nature of the beast.
