00 |
First Record. MFX uses this Code to indicate the first call to the COBOL exit and that the first record to leave Phase 3 is in the RECORD-UP area. |
|
04 |
Most records. This is used for all calls except the first one when there are records in the RECORD-UP area. After Code 00 has been issued, Code 04 is passed to the exit until there is no record for the sort to pass to the RECORD-UP area. |
|
08 |
All records passed. This indicates that the last record has already been processed by the exit. Do not attempt to reference the record again. No more records will be passed to the exit routine. Note that if MFX is not passing any records to Phase 3, 08 will be passed every time including the first time. |
