1,024 additional Registers on the CL

[Ángel Martin]

you guys are insatiable... this is getting very tricky, the code is looking amazing so far... I just completed XISG _ _ _ and XDSE _ _ _ so with that rich function set migrating programs should be getting close to becoming a breeze...

I have an idea to get it done but for program operation the "mask" will need to be stratospheric, i.e. add 3,072 (0xC00) to the index:

expanded: from 400 to 3FF - normal index#
IND "expanded": = adds 1,024 to index
IND ST (1-16): adds 2,048 to st_index
IND ST (standard) regs, per current SIZE): adds 3,072 to index

debugging is very tedious, can't use V41 or other PC tools... it's hard work but when completed (and we're 95% there) I trust this should give a nice boost to the CL world.
