Command Definitions (HPMERGEEND-LOGSTATUS)
HPMERGEINIT
intrinsic to retrieve merged records.
postprocessor procedure (reserved)
Do not specify this parameter, but maintain parameter position.
keysonly 32-bit signed integer by value (optional)
Flag that determines if only keys are sent as output. If set to 0, the entire
record is sent as output. If set to any value other than 0, the key fields are
concatenated together with he major key on the left and the remaining
keys following. Default: 0
numkeys 32-bit signed integer (optional)
Number of keys used during the comparison of records. This parameter
can be either equal to or greater than one. If you specify the
numkeys
parameter, you must also specify the keys parameter. Together, numkeys
and keys describe the way records are merged.
keys 32-bit signed integer array (optional)
Passes information about the keys used during the comparison of records.
If you specify the
keys parameter, you must specify the numkeys
parameter. Together, keys and numkeys describe the way records are
merged.
For each key, there are four entries in the array.
The first element gives the position of the first byte of the key within the
input record. The second element gives the number of bytes in the key. The
third element indicates the type of data:
