Hi 4tH-ers!

We've been pretty busy! First during a chat with Ron Aaron, author of the wonderful 8th compiler, I got an idea. What if I made the symbol table part of the 4tH structure? You could do cool things like:

4tH message: No errors at word 76
Object size: 76 words
String size: 85 chars
Variables  : 1 cells
Strings    : 0 chars
Symbols    : 9 names
Reliable   : Yes

Yes! Append labels to already compiled code. Note it only works for things that do NOT compile to a literal, but those are quite a few. As you can see, I updated the report itself (unchanged since 1994) as well.

And we applied a few fixes that boost the compilation performance with 25%! Yes, even on my simple P4, 4tH compiles with a rate of 10 MILLION lines per minute.

Keep you posted! And code in SVN.

I didn't realize using a Pentium 4 was still legal.

Well, it isn't here in Holland, but I'm the leader of a ring of P4 rebels that keeps the platform alive. There getting closer, but they haven't caught us yet? Wait, who is knocking on the door at this hour? I'll be right back.
