Hi Jacques,
You might be able to use the /SID - Session ID switch, that Brian
Hancock mentioned in his post of 30 Mar 2014 08:18:29 +1100.
I haven't used this feature, but it sounds like what you are trying to do.

Hi All,
It was from 1986 thru 1993 that I programmed a comprehensive
application in DataPerfect (appr. 80.000 lines of code, comprising
30 interrelated panels) which administered the complete workflow for
an advertising photography and or movie production studio. A last
set of modules that was added to the application, consisted of an
automated bookkeeping add-on, that would function also as a stand-alone.
At that time, believing computers would not run any faster than they
did, I programmed each relative link thus, that to obtain an
absolute unique record in the indexes, it had to generate a hidden
date and timestamp at the creation of each new record. When closing
the book-year at years end, through the printer level, the data
would be changed as to block the original data input. This panel
replicated the original (separate) data-input panel and could also
be used to recover old data whenever something would corrupt the
financial files.
Until now the application has continued to work flawlessly. But with
the speed of computers these days, the system does not work any more
when reconstructing the records, because within one second many
records can be generated carrying the same time stamp, thus
corrupting the index(es) for those newly generated records.
Reprogramming this time stamp to a <FORMAT:~GZZZZZZZZZ9::IH~> is not
a good option, given that over time millions of numbers must be
generated; all being unique! Thus I kept one old computer with an
AMD 386 40MHz. processor. Having that system processor running at
half speed, would be sufficient to keep generating records at less
than one record a second, as to comply with each record keeping a
unique value in the indexes.
With this sole computer becoming older and thus more unreliable,
Something must be done to keep the system up and running. I have
tried to find an answer in forcefully slowing the clock speed of
present day processors, but nobody has an answer to that so far.
Another option would be a math formula (applicable to DataPerfect
DPIMP compilation) that could generate unique coding (either
numbers, or a combination of numbers and letters).
Does anyone have a suggestion?
Jacques
