I gathered that from a vfy of it.

I keep hoping that someday, someone who understands editors, will write 
one that uses the same memory paging techniques that MyRam does.  That 
would give it a buffer of whatever memory there is to spare, in my case 
about 1.7 megabytes.  ;)  But with only 24k of it, 3 of the 8192 byte 
blocks, actually mapped in at any one time.

Then I could have a comment 4 lines long to describe one assembly 
instruction.  Thats overkill of course, but the descriptor header above 
a subroutine is too often factless.  I don't want to write a novel but 
sometimes there is no halfway that is an adequate description.

Thanks Luis.
