I think if you pay Borland $1000000, they might let you *peek* at the source code...

Intense parsing
Intense error recovery

$1,000,000 might get you a glimpse, but if you are ready and willing, go to the president of Borland with a cigar and go from there.

Trying to write a compiler is tedious and a pain in the ass. Once you get past the parsing, you have to generate decent optimized asm code out of the language, it's not an easy task.

I tried writing my own INTERPRETER, that is, there were no EXEs.  Wow, what a pain.  It worked okay, even fairly fast, but it was not worth the effort (the language was more cryptic that assembly and it was slower than BASIC)! :-)

What do you want to accomplish?  If this is for fun, then by all means try it, but otherwise, I fail to see the point :-)

Who cares?  If you really want to dive into a good C++ compiler's source, check out gcc.  Pick up a good book on compiler design too.  You could get lost in there for years.

This site doesn't have a C++ compiler that I know of, but it contains some useful info that might be of interest to you.

Visual Parse++ looks promising.  Check out:

http://www.sand-stone.com/frvpdesc.htm

Search the web for bison, lex, flex, yacc, byacc, and you'll
find other parsing tools, as well.

Chances are good that Borland uses its own custom parser.
Chances are also good that you won't find out.  :)

If you get a job programming for Borland, they might pay you to peek at the source code.
