I don't think that this is common usgae so much as me getting confused
by starting on VAX/VMS systems before DOS and then heading into
the world of UNIX comminded with shouting ides to people across
offices and hoping they guess what I mean if I say "pipe it to file"

I was always told that it was mathematician that where lazy.

Hmmm, I've got that one on my shelf somewhere time to hunt it our
perhaps.

I think it's time to try again as I want to have a lock at phil karns
new version of ka9q which has soundblaster support, just what this
does or why you'd want it I don't know but it sounds interesting.

On the plus side of course the JNOS code I've got supports both ems
and xms memory, which should help matters.

Sounds familliar, I've worked on WP macro's like that, some of the
stuff "bespoke software" writers do is scary....

Speaking of alternative versions I found the problem with 
the dialer script I was working on, it seems to be that
it's objecting to the carrier detect /* &C1 */ in my
modem init string, I removed that and it's fine.

Now I've just got to check that all my code is reasonably
commented, check the documentation such as it is, and then
I can use it, and put it to oneside for a bit. Unless anyone
else would like to play with it a bit.
