=—repeat previous line command

The = (repeat) line command repeats the line command that was most recently used. This command is most helpful when the same TSO command, CLIST, or REXX exec is to be invoked for more than one entry in the directory list.

For example, if you just invoked a CLIST named TESTABC with file /u/mydir/data (by typing TESTABC to the left of filename data in the list for directory /u/mydir) and now you want to invoke TESTABC with file /u/mydir/data2, you can type = to the left of filename data2 instead of retyping TESTABC.
