I am using the 'Demon-supplied' DIS v1.29 UK DOS software with PCElm v1.11
and SN v1.30.03.  I run this in a DOS session under OS/2 and connect using
the OS/2 32-bit port of NET.EXE {and it all works splendidly}.

I just had an "Insufficient memory" warning when calling the external
spellchecker from the external text editor viewing some messages within
PCElm. This went away {and everything also speeded up a bit} when I raised
the EMS memory allocation for the session from 2Mb to 4Mb. So it's all flying
nicely again, but it just prompted the thought of trying to optimise the
memory settings for running DIS.  I can vary the amount of DPMI, EMS and XMS
memory available to the DOS session, but equally don't need to 'waste' any of
one particular type if the DIS software can't make use of it.

I am guessing from the behaviour so far that DIS can utilise EMS memory, but
not DPMI and, probably not, XMS.  Could anyone confirm this or tell me what
the actual 'answer' is on DIS' memory utilisation?

Thank you.
