3525 Error Recovery Routine
Source: GA21-9124-3 3505 Card Reader
3525
Card Punch
Subsystem Component Description
Before any programmed punch and/or print retries are performed, the operator must
remove all cards that must be completely or partially reprocessed. Your source pro-
gram error recovery routine can help the operator to decide which cards need to be
removed. Some of the information your routine could provide is:
1. The number of cards to be removed.
2. The location of the cards to be removed.
3. Identification by data content of the cards to be removed.
4. The number of blank cards to be put in the 3525 for the recovery pro-
cedure.
The error recovery routine should then punch and/or print the data for the card that
must be completely reprocessed. Then !lunch and/or print the data for the next card
that must be partially reprocessed. The error recovery routine can then retum to the
normal source program to finish processing that next card.
For specific recovery techniques, be guided by the error message you receive from the
System Control Program in use.
