The CLEANUP= directive will clean up after the temp files that are
      created during the compile and link process. Most notably, the two
      junk files from the ERRFILE= and ERRBAT= directives (which always
      have defaults) are cleaned up after (this happens automatically).

      Of course, you can use this to keep any filespec deleted out of
      your working directory.

      For Example:

      CLEANUP= *.TMP

      If you wish to suppress the automatic deletion of the ERRFILE=
      and ERRBAT= files, use the following example:

      CLEANUP= NONE
