Not really - see below

That's right - if you want to use large you must recompile the source,
which is only available (or should only be available) to registered
users.

Then you can use the enviroment variable M2MODEL to set which model to
compile to, or specify it each time you compile something.

Wrong - it is brought about by the PC architecture. It is applicable to
a wide variety of programming langauges - all that don't just execute in
the tiny model (like BASIC).

So in Modula 2, C, ASM, etc the model makes one heck of a difference.
