SORT-MERGE/XL Programmer's Guide

Merging 

MERGE/XL only merges files that have already been sorted.  For example,
if you merge a file that contains information on newly hired employees
with a file that contains information on current employees, each file
must have the same record format and be sorted by the same information.
If you merged two such files, each sorted by last name, you would get one
output file with all employees sorted by last name.  The output file
would have the same information and format as the two input files.

Figure 1-3. MERGE/XL Operations The intrinsics used for merging are: HPMERGEINIT Initializes MERGE/XL utility and begins the merging operation (required). HPMERGEERRORMESS Returns error messages. HPMERGEOUTPUT Allows output to be by record (instead of file). HPMERGEEND Ends the merging operation (required). HPMERGESTAT Prints out merging statistics. HPMERGETITLE Prints out title information for MERGE/XL.
NOTE For merging operations, use only the merge intrinsics. Do not mix sort and merge intrinsics.
