INPUT (MERGE/XL) 

Within the MERGE/XL subsystem, the >INPUT command specifies the sorted
files to be merged.  Refer to the SORT/XL >INPUT command for information
on how to use the command within that subsystem.

SYNTAX 

     >I[NPUT] {fname1,fname2}[,fname3]...[,fnameN]

PARAMETERS 

fname                     The fname parameter specifies the actual file designator.
                          $NULL is not a valid input file.  The order in which the
                          input files are specified is important in that records with
                          equal keys are positioned according to the order of the
                          files in which they appear.

                          Notice that parentheses are not used with >INPUT command in
                          MERGE/XL.

DISCUSSION 

Unlike the SORT/XL >INPUT command, the input files are not enclosed in
parentheses.  The order in which the files are specified is important
only in that the records with equal keys are ordered according to the
order of the files in which they appear.  If more than one >INPUT command
is entered, only the last command is effective.  See the discussion under
the SORT/XL >INPUT command for information about file equations.

EXAMPLE 

The following example shows how to merge three previously sorted files,
SORTED1, SORTED2, and SORTED3, into a single, new, output file named
MERGE1:

          :MERGE    

          HP32214A.01.00  MERGE/3000 THU, JUN  4, 1987,  9:45 AM
          (c) HEWLETT-PACKARD CO. 1986

          >INPUT SORTED1, SORTED2, SORTED3    
          >OUTPUT MERGE1    
          >KEY 1, 11  
          >END
