If you want the lower level features with a language very similar to
Pascal, I recommend the TDI Modula 2 compiler.  The documentation is
superb and has many examples for using the GEM operating system.  In 
fact, even if I was going to do everything in C, the manual would be
a significant help in deciphering the developers kit manuals.  I have
been using it currently with one double sided drive(my other drive is
in the shop) and can compile/link a reasonbly sized graphics program
in about 3.5 minutes.  The package has all of the bindings necessary
to talk to GEM.  The language allows address manipulation as well as
inline machine code(hex codes, not mnemonics).

For the $60-$70 price tag, its well worth the price.
