Just thought I would put my two cents worth into the discussion...

I also bought the MIX compiler for the price, and the fact that it will
run on my HP150 (generic MSDOS).  It has been pretty good for the price,
but I've had a few problems, too.

First, the enumerated data types don't assign constants to the
identifiers.  Example:

enum day {sun, mon, tue, wed, thu, fri, sat} next_day;

.
.
.

switch (next_day) {
  case sun: (whatever)
  
  case mon: (whatever)

etc.  The MIX compiler gives an error at each case statement, saying
something to the effect that the compiler was expecting a constant, as
it should.  But, it was apparent that the enum statement did not assign
sun, mon, etc. as constants.  Anyway, I never got it to work.

Next, I was trying to open PRN: as a binary file, to perform a screen
dump.  I used a routine which changed the printer device to raw mode
as well.  The program never worked, as the program never printed the
data in raw mode (according to my dos routine, the printer *was* in
raw mode).  After transferring the program to Datalight C with the
minor changes necessary for the DOS calls, the program worked just
fine.  So, I know that the programming was correct.  Anyway, I called
the MIX company, and they weren't helpful at all.

I bought the Datalight Optimum C package, and have been very pleased
with it.  Compiles are very easy with the controller program they
give you, and the make utility is nice.  I would recommend this
compiler over MIX C any day.

If anyone has any comments as to what I may have been doing wrong (if
anything) in my MIX programs, let me know!
