AP-D3 operating-system and dbms

In the Pick-AP-D3-7.0.8.10 guest operating system
running on a SCO Unix host operating system
my customer now finds that ACCOUNT-RESTORE is reading and restoring
the first 512 bytes of an account file from his file-save tape,
then skipping the next 15,872 bytes (31 blocks) of the account-
save tape, then restoring the rest of the account.

Perhaps this is related to the 16,384 tape block size.
... Perhaps not ...
Changing the tape block size to 500 doesn't change the problem.

Copying the file-save tape to a unix disk file
in pick-style "virtual floppy" format
(with 12 ascii nulls every 512 bytes
and a tape block length of 500
and ascii "EOF" messages serving as virtual tape marks)
and changing the tape label length from 0x4000 to 0x01f4
and then restoring from the virtual-floppy
doesn't change the odd behavior of the ACCOUNT-RESTORE verb.
It still reads a block, skips 31 blocks, then restores all the rest.

Also, despite losing some items and restoring at least one item
with the wrong item length, and sometimes losing some entire files,
none of the ACCOUNT-RESTORE performances are reporting any errors.

My customer has now decided to move his data from his old Pick-
based application to a new and unreliable application
based on Microsoft SQL Server.

Another consultant has been trying to convince the customer
to move the data to JBase or UniData but the customer
just wants to get as far away from "Pick" as possible.
