Hmmm. Seems right now you're a little overpaid or underworked? Have you already done a compiler, complete with code generation and error handling? And you'll need a runtime library, too. (Quite some time ago, I did have to build - rebuild, to be precise - a small compiler. It was for a simple special [PLC] language, no objects, just standard control constructs and mathematical expressions, and maybe even subroutines. It compiled to assembler code, and the goal was to achieve an appreciable reduction of code size compared to the existing compiler. It amounted to a complete rework, which took me a couple weeks to write and quite some time to test before it was delivered to the customer. It worked mainly as intended, except for a nasty problem that occured with one specific program, where it always crashed... Turned out this was due to an [undocumented] assumption in the parser generator, which didn't expect anything beyond the 7-bit ASCII character range - and this program contained exactly one Umlaut, in a comment... Took another couple weeks to find, although it was fixed in a couple minutes then.) You're facing quite a challenge here, Object Pascal isn't a simnple language at all, especially because of the rather intricate data structures to be built and managed. And doing that _fast_ is another, twofold, challenge - you have to make the compiler _work_ fast, and have to make it produce code that's working fast. That's certainly an interesting feat, but it'if s not done full time, it will almost certainly become a never ending story... Anyway, I wish you good luck!
