Hyper C and Davex

[teke@milton.ccs.itd.umich.edu (Jeff W. Schroeder)]

Hi all:
 
 
This is a new one for me.  I have never posted to
the apple II programmers newsgroup before since all I
know how to program in is basic...  well enough rambling.
 
The reason I am here is I want to learn to program in C.
Problem is I only have an apple IIe.  Could someone please
point me in the direction of a compiler and some literature
that can get me started?  I have a copy of hyper C, but thats
it.  I don't really know where to begin.  I was told that the
flavor of C supported by hyper C is something like K&R or KNR?
C?  Couldn't find any books describing it at the book store.
Just PC stuff like C+ and C++.
 
At work we will soon be implementing a geographic information
system.  It will most likely run on either a 486 or Pentium
PC or a unix based mini.  I would like to get a jump on learning
C at home and fiddle with the apple.
 
I currently utilize Davex as a prodos unix-like shell.  Is davex
written in C or assembly?  I have tried to contact Dave Lyons regarding
this but have got no response.  I would like to register my copy
and get the full blown set of commands and documentation, but I
have read that he is no longer supporting it or collecting on it.
 
Lastly...
 
I read somewhere that there is a unix os called opix available
for the IIe.  I haven't been able to find it on any of the FTP
sites.
 
Hope to hear from someone soon!
 
Apple II!!!
 
 
 
Peace...
