Use this macro to remove a data set reference and unneeded indexes.

The format of the CATALOG and CAMLST macros is:

>>-+-------+--CATALOG--list_addrx------------------------------><
   '-label-'                        

>>-listname--CAMLST--+-UNCAT--+--,name_relexp------------------><
                     '-UCATDX-'                 

list_addrx

Points to the parameter list (labeled listname) set up by the CAMLST macro instruction.

UNCAT or UCATDX

Code this operand as shown. Either UNCAT or UCATDX can be coded but, in either case, unneeded indexes, with the exception of the highest-level index, are removed along with the data set reference.

name_relexp

Specifies the virtual storage location of the fully-qualified name of a data set or index level. The name cannot exceed 44 characters. If the name is less than 44 characters, it must be followed by at least one blank. In a DFSMShsm environment, if the data set name is less than 44 characters, it must be padded with blanks until the 44-character length is reached.
