isforth.asm

This is the main source file for the IsForth kernel. It includes all the other kernel sources and defines some global variables etc. It also contains the entry point and initialization routines.

VER

This %define sets the release version number of the kernel. The high byte of this 16 bit value is the major version number. The low byte is the minor verison number.

MEMSZ

This %define sets the memory size that the kernel will later sysbrk out to. The default size of this is exactly 1 Meg.
