JBA ML - "WARNING: Item has previously been deleted."

Program IN002 - Menu 2/INM - When attempting to re-add items to INP35 that have
been previously deleted you receive this warning message "WARNING: Item has
previously been deleted."  The user is required to press the reset key.  If the
user attempts to proceed past the warning the program fails and produces a
program dump.

Here's a snippet of that dump:
Program Name . . . . . . . . . . . . . :   OSLINP3/IN002
 Last File Used . . . . . . . . . . . . :   INP35F1P
 Last File Status . . . . . . . . . . . :   01021
                  attempts to write duplicate record (C G S D F).

Further more, an incomplete INP35 record is created thereby populating INP35
with corrupt data.
(The only way for us to then clean up the mess is to delete the corrupt INP35
record, the INP35F record must be deleted manually as well.)

During the Item deletion routine 26/INU (which leaves a great deal to be desired
in terms of completeness) INP35F in particular is not purged of the deleted item
records.

Does anyone else have any experience with or insights into this problem...?

Thank you.
