Description:
We don't want to have to back up the entire doc file when we do a global change with p_manage_21 (or global fix-in-place with p_manage_37). But if the updates are incorrect, we need to be able to recover from them.

Resolution:
The input file to p_manage_21 is a file of doc numbers (produced by p_ret_01 or an OPAC search). p_manage_37 can have such a file as input (or it can have ALEPH sequential records as input). In the case where the input to a job is a file of doc numbers, you can do this:

1. Run p_ret_01 with output file "doc_numbers"..

2. Run p_print_03 with Input file "doc_numbers"; Output file, "prt03out"; Format, "ALEPH Sequential"; Fix routine, "NONE"; and Character Conversion, blank..

3. Run p_manage_21..

4. If you need to recover the original records, run p_manage_18 with "prt03out" as the input file..

p_manage_37 is exactly the same.

print-03 could be used in a similar fashion to back up doc records being updated by the manage-37 or manage-18 Services or deleted by the manage-33 Service.
