Major:: 22 of 64 left

I forgot to mention that 6 of the taken are permanently reserved
to prevent jumping into code and having anything execute--inde-
pendent of whether --E is permitted. So only 36 of 64 are in use.

Mem:::: 32 of 64 left
2-OP::: 33 of 64 left
3-OP:::  4 of  8 left
1-OP::: 56 of 64 left
