That define is in the vvp code generator, and not part of the vvp run time. In fact, it is an arbitrary value and used to size an allocation map. That map helps with thread bit allocation, which is much like register allocation in a standard compiler. The devel vvp no longer has a limit of 64K of thread bits, that 256K limit is entirely arbitrary (but convenient) in the vvp code generator. - -- Steve Williams "The woods are lovely, dark and deep. steve at icarus.com But I have promises to keep, http://www.icarus.com and lines to code before I sleep, http://www.picturel.com And lines to code before I sleep." -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.5 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFEGbtDrPt1Sc2b3ikRAlrYAJ0RMEf8gzimpOre3cJy3GGkKWi/bgCgvNQB FnlHpXtTOa721RdbzRB9Eto= =h7GR -----END PGP SIGNATURE-----
