After reading the docs for CWSPARAM, I'm not sure I understand two of
the parameters. I get my DPMI services from OS/2, but my users may need
to use CWSDPMI, so I need to advise them on proper settings.
> Minimum application memory desired before 640K paging ? [256Kb]
> This parameter determines the threshold which CWSDPMI
> should start using DOS memory as DPMI memory.
What is it that is crossing a threshold? Does the default 256K value mean
that DOS memory will be used as DPMI memory if unused extended memory drops
below 256K?
> Paragraphs of DOS memory to reserve when 640K paging ? [3840]
If a program has a shell-to-dos function, does this parameter control how
much memory is available in the shell?
In general, how should I advise my users to set these options for a program
which is relatively small (~200K), but may require arbitrarily large amounts
of memory for data and may want to spawn a DOS program or DOS shell?
