I have a Megamax C compiler Version 1.1 and would like to utilize
the linea routines from the in-line assembler.  Specifically, I
only need to write a pixel to the screen ($a001 - linea opcode).
The information that I am currently using, the ABACUS ST Internals
book, is not very clear about what variables must be declared
and initalized for the routines to function.  Megamax on the other
hand is not very clear with their explanation of variable passing
to and from the assembly routines.  Would someone please be willing
to recommend a good reference guide for the linea routines or
better yet provide a simple example of the code for the Megamax
C compiler.   

			Thanks in advance.
