Has anyone on the net used Lahey Personal Fortran.?  How good is it compared
with MS Fortran?  DOes it support a coprocessor(80x87)?

I have used Lahey Personal a little bit.  I would rate it very favorably
against MS Fortran.  I would qualify this, because I have never used it
for a large project.  Generally, I compile numeric routines and link
them with a larger C program.

Yes it does support 80x87 coprocessor. Floating point emulation is supported
as well.

I have also been favorably impressed by the responsive support from Lahey.
Not many companies support $100 products this well.

(An attempt at a follow-up on an existing article bombed --- and our one
UNIX guru is out of town till 24 June.  Maybe I can post this directly
and get it through . . .)

From the last go-round of this question, here's the information I've
gotten (thanks to David Marden [pyuxf!mdc@bellcore.bellcore.com -- or is
that just mdc@pyuxf.UUCP?], who collected the info):

Lahey Computer Systems, Inc. at (702) 831-2500 offers Lahey Personal
Fortran --- this is for smaller programs with one-segment limitations:
you can have 64K code, 64K data, and 64K stack.  The list price is $99,
but there is an educational discount (10 copies or more, or faculty
member evaluating the product) bringing that down to $60 each.  There is
also a tool-kit that one can get to accompany the Fortran that runs for
$20.  I can't comment on the product since I only ordered it last Friday
and today received the billing (not the product since I went for cheap
shipping) --- another $85 squeezed out of my Visa card.

Lahey has larger products, but here I'm going purely from memory (my
notes reflect my need to teach an intro Fortran course next Spring) ---
there's one that can use the full address space of the 8086/8088 (640K),
and another that can use the full address space of a ?80286/80386?;
these, of course, cost in the K$ range.

Disclaimer:  I have no connect with Lahey aside from paying them $85.
