   PROBLEM DESCRIPTION:
     THERE IS NO WAY TO CATALOG A DATA SET ON "THE CURRENT SYSRES".
       CATALOG ENTRIES FOR SINGLE-VOLUME NON-VSAM DATA SETS SPECIFY
       THE DEVICE TYPE AND THE VOLUME SERIAL NUMBER.  THERE IS NO
       WAY TO INDICATE THAT THE DATA SET WILL BE FOUND ON WHICHEVER
       VOLUME HAPPENS TO BE THE CURRENT IPL OR SYSTEM RESIDENCE
       VOLUME.

       THIS USERMOD UPDATES ALLOCATION'S VOLUME/UNIT TABLE COMPLETION
       ROUTINE TO RECOGNISE THAT WHEN THE VOLUME SERIAL IN THE
       CATALOG ENTRY OF A SINGLE-VOLUME NON-VSAM DATA SET IS SIX
       ASTERISKS, THE DEVICE TYPE AND VOLUME SERIAL SHOULD BE
       RESOLVED TO BE THAT OF THE CURRENT SYSTEM RESIDENCE VOLUME.

       NOTE THAT WITH NO CHANGE TO IDCAMS, A COMMAND SIMILAR TO
         DEFINE NONVSAM(NAME(DS.NAME) VOLUME(******) DEVT(3350))
       WILL BE SUCCESSFULLY PERFORMED FOR VSAM (BUT NOT OS SYSCTLG
       OR CVOL) CATALOGS.

       UNLIKE MVS/SP, DEVT(0000) IS NOT SUPPORTED - A VALID DEVICE
       TYPE MUST BE SPECIFIED.  ANY SPECIFIED DEVICE TYPE IS REPLACED
       BY THE IPL VOLUME'S DEVICE TYPE WHEN THE SIX ASTERISKS ARE
       REPLACED BY THE IPL VOLUME'S VOLUME SERIAL NUMBER.

   PROBLEM DESCRIPTION:
     EACH VOLUME MUST BE NAMED IN PARMLIB TO SET MOUNT ATTRIBUTES.
       EVERY VOLUME REQUIRING NON-DEFAULT MOUNT ATTRIBUTES MUST BE
       EXPLICITLY NAMED IN THE ACTIVE VATLST MEMBER OF SYS1.PARMLIB.
       THERE IS NO PROVISION TO ASSIGN ATTRIBUTES TO A GROUP OF
       DASD VOLUMES WITH A SINGLE SPECIFICATION IN VATLST.

       THIS USERMOD UPDATES THE VOLUME ATTRIBUTE PROCESSOR (IEAVAP00)
       TO ACCEPT GENERIC MASKS SUCH THAT A SINGLE VATLST STATEMENT
       CAN ASSIGN THE SPECIFIED MOUNT ATTRIBUTES TO EVERY ONLINE
       DASD VOLUME WITH A SERIAL NUMBER MATCHING THE MASK (AND WITH
       A MATCHING DEVICE TYPE).

       GENERIC MASKS FOR VOLUME SERIAL NUMBERS MAY CONTAIN ASTERISKS
       AND PERCENT SIGNS WHERE EACH ASTERISK REPRESENTS A GROUP OF
       ZERO OR MORE CHARACTERS AND EACH PERCENT SIGN REPRESENTS
       EXACTLY ONE CHARACTER.  VOLUME SERIAL CHARACTERS CORRESPONDING
       TO THESE MASKING CHARACTERS IN A COMPARE WILL BE CONSIDERED TO
       MATCH.

       CONSECUTIVE ASTERISKS SHOULD NOT BE CODED EXCEPT FOR THE
       SPECIAL MASK OF SIX ASTERISKS WHICH CAN BE USED TO SPECIFY
       THE CURRENT IPL (OR SYSTEM RESIDENCE) VOLUME.

       TO SPECIFY AN EXACT VOLUME SERIAL CONTAINING AN ASTERISK OR
       PERCENT SIGN, CODE AN 'S' IN COLUMN 7 INSTEAD OF A COMMA.

       THE ONLY GENERIC MASK RECOGNISED FOR THE DEVICE TYPE FIELD IS
       A SINGLE ASTERISK WHICH SPECIFIES THAT ALL DASD DEVICE TYPES
       ARE ACCEPTABLE.  THIS DEVICE TYPE GENERIC MASK CAN BE USED ON
       VATLST STATEMENTS WITH A SPECIFIC OR A GENERIC VOLUME SERIAL.

       IEA166I NO VOLUME MATCH
       IS A NEW MESSAGE ISSUED WHEN NO VOLUMES WERE FOUND TO MATCH
       A GENERIC VOLUME MASK.

       IEA855I MESSAGES WILL CONTINUE TO BE GENERATED WHEN NO VOLUMES
       MATCH A SPECIFICALLY NAMED VOLUME.

   SPECIAL CONDITIONS:
     ACTION:
       THIS SYSMOD SHOULD BE ACTIVATED SIMULTANEOUSLY WITH ZP60042.
       A "CLPA" MUST BE PERFORMED AT IPL TIME FOR THIS SYSMOD TO
       BECOME ACTIVE.
