HS>There are differences between them.
There are some differences, _but_ the differences are NOT relevant for
a project like this.  They are the same language.  It's the 'frills'
where they differ.  BC30 has better optimizations, utilities, etc.  BC
is for the professional programmer who needs the extras, and TC30 is for
the hobbiest who can get by without the extra utilities and better
optimizations.  But the language they implement is identical.  They have
the same parser, they have the same Borland extensions, etc.
HS>CB>As for the large memory model....  that isn't going to work!  The .asm
HS>CB>modules clearly require the memdium memory model.  That's also what the
HS>CB>.PRJ has set.  You just simply can not compile with the large memory
HS>CB>model. It'll give you fatal compilation errors.
HS>What did you expect? A magical fairy to make it compile in a different
HS>compiler? you have to change a few things, even if it means to edit an 
asm
HS>file and replace a medium with large.
Pffftt..  The program is _designed_ for the medium memory model.  Not
for small, not for large, not for huge.  Regardless of the compiler, it
is _designed_ for the medium language.  Switching to a very different
compiler may require some changes to the code, but very unlikely to the
memory model. Changing from BC30 to a related, dumbed down version of
the compiler (ie: TC30) should require few to no changes.
As you gain some experience with computers and programming, you'll
realize what should and should not happen / be needed, etc.
