 1)  After editing the directory, do these commands to "reset" DIRMAINT.
       DIRM INITLZ
       DIRM SORT
       DIRM CMS ERASE USER PREINITL
       DIRM CMS ERASE USER PRESORT
 
 2)  The format for using automatic minidisk allocation when adding is
       MDISK 191 3380   AUTOG cccc   SHARED MR
       MDISK 191 FB-512 AUTOG bbbbbb USER   MR      (for ALMVMJ)
 
 3)  The line form for some commands are
       DIRM AMD userid vaddr devtype start size volser    (SYS *
       DIRM AMD userid vaddr x       AUTOV size volser    (SYS *

 4)  To replace a file like EXTENT CONTROL on DIRMAINT's 191 disk,
       Get a copy of the file, modify it, and store it on your a-disk.
       DIRM FILE EXTENT CONTROL
       DIRM RLDData           To reload the modified file.
 
 5)  To add one of the userids for the full-pack minidisks, you'll get
     an extent error when you try adding the userid.  To avoid this,

       DIRM ADD userid
       DIRM EXTNchk ON        To turn it back on.
