Parameters
status 32-bit signed integer by reference (optional)
Returns the status of the HPMERGEINIT call. If no errors or warnings are
encountered,
status returns 32 bits of zero. If errors or warnings are
encountered,
status is interpreted as two 16-bit fields.
Bits (0:16) comprise
status.info . A negative value indicates an error
condition, and a positive value indicates a warning condition. Refer to the
MPE/iX Error Message Manual Volumes 1, 2 and 3 for a description of its
value.
Bits (16:16) comprise
status.subsys . The value represented by these bits
defines the subsystem that set the status information. The subsystem
identifier for HPMERGEINIT is 196.
inputfiles 32-bit signed integer array (optional)
Passes the file identification numbers of the input files to be merged. The
last element of this array should be set to zero. If the files are opened with
either the NOBUF or MR (multirecord) access option, MERGE/XL program
performs the buffering and blocking/deblocking.
preprocessor procedure (reserved)
Do not specify this parameter, but maintain parameter position.
outputfiles 32-bit signed integer array (optional)
Passes the file identification number of the output file in the first array
element. If the file is opened with either the NOBUF or MR (multirecord)
access option (
aoption ), MERGE/XL performs the buffering and
blocking/deblocking.
If you do not specify this parameter, you must call the HPMERGEOUTPUT
