Subject: Lat/Long Software?

NetLandians,

I'm looking for public domain source code (BASIC, Pascal, Assembler, I don't
care) that will work with Latitude/Longitude, geographic coordinate, and
polar coordinate data.

I have some Army Aviation people that would like to fiddle with that, trying
to find fast ways for flight calculations.  (I know this has all been
done before, but they want to learn.)

I read the article in Byte Mar 85 on navigation, but that's sextant-based.
I need something that, given various ways of locating yourself, will help
to compute time/distance factors.

There's a nice 747 flight simulator program that does a lot of this, but
it's all built into a simulation, and I don't have the heart to peel it out!

Second request (for me):  I can get CDOS (Cromemco DOS) formatted software
from the USAF TAC micro office at Langley AFB, but have no Cromemco Z80
machines to read the disks (5.25 soft sector) with.

Anybody got the tricks to read CDOS floppies?  Is it just a matter of disk/
track/sector format?  There's stuff in SIGM to let Cromemcos read CP/M,
but I've found nothing the other way around.

Thanks in advance,
