The Retrieve Next  Name command takes  a name value such  as 'ABC0001',
adds  1 to  the digit  portion, and  returns  the next  name 'ABC0002'.
The  number portion  of the name  may contain 1-9  digit positions, but
must be  in the  trailing position of  the name.   A  rollover such  as
from  a name  'ABC9999' causes  an escape  message.   RTVNXTNAM  may be
used for objects, members, or your own internal naming convention.

Assume you  want a new member name by adding  1 to the last member name
in the  file.  Assume  the members  begin with  ABC and  have 6  digits
following.   The  first  member name  used was  ABC000001.   A  typical
series of commands would be.

             DCL       &LSTMBR *CHAR LEN(10)
             DCL       &NEWMBR *CHAR LEN(10)
             ADDPFM    FILE(xxx) MBR(&NEWMBR)

If  the last member  name used was  ABC000456, the new  member would be

The NBRDIGITS  parameter  identifies  the  number  of  digits  in  your
naming  convention.   These are  checked  to ensure  values  0-9.   The
CURNAM parameter must  be a valid object name.   It cannot begin with a

If  the CURNAM  value is  ABC99999, an  escape message would  be issued
because a rollover of the number occurred.

RTVNXTNAM escape messages you can monitor for

      TAA9891    A rollover has occurred.  A new name cannot
                  be assigned.

Escape messages from based on functions will be re-sent.

RTVNXTNAM Command parameters                          *CMD

   CURNAM        The current name  to add 1 to.   The number of  digits
                 can   be  a   length  of   1  to   9  such   as  'An',
                 'Annnnnnnnn',  or 'ABCnnn'.  The name  must be a valid
                 object name  on the  system.   The number  must be  in
                 the  trailing  positions.     Blanks  may  follow  the

                 It  is  valid  to have  a  name  such  as ABC1234  and
                 specify NBRDIGITS(2).  The  next name retrieved  would
                 be ABC1235.

   NBRDIGITS     The number  of trailing digits  in the  number portion
                 of the  name.  If the CURNAM is  ABC101, the number of
                 digits would be 3.

   NXTNAM        The  next name  that has been  created by  adding 1 to
                 the  current  name.     This  is  a  required   return
                 variable that must be declared as *CHAR LEN(10).


Because RTVNXTNAM returns  a variable, the command may  only be used in
a CL like program.
