Issue the LISTALC STATUS command to see the names of all data sets allocated to SYSEXEC and SYSPROC.
To see what data sets are already defined to SYSEXEC and SYSPROC at
your installation, issue the LISTALC command with the STATUS keyword.
You then see several screens of data set names that might look something like the following. Scroll until you find SYSEXEC and SYSPROC.
In this example, one data set ISP.PHONE.EXEC is allocated to SYSEXEC, and three data sets ICQ.INFOCTR.ICQCLIB, SYS1.TSO.CLIST, and
ISP.ISPF.CLISTS are allocated to SYSPROC. (When a space appears below the data set name, the data set is allocated to the previously-specified file (DDNAME)).
I got this from TSO/E REXX User's Guide for OS/390.
