PCT instruction... a musing...

Here is a thought... if the PCT instruction is implemented, it would 
protect that instruction from being overwritten for one attempted write
(in which afterwards it would go into the regular state again).  

The question is this... if you protect your own instructions, then should
that program still be allowed to overwrite the protected instructions, or
does the protection protect the instruction from everything, including the
process that protected that instruction in the first place?  

Incendentally, my Deluxe package is nearing the mark of its release.  I
still have to add the Write Limit in and finish the PCT instruction (which
will only take me a minute...).  I currently have the ANSI display (which
will work on both PC's and Unix), the Curses display and the Summary display
for the dumb terminals.  I will also add the PCTEXT display tonight which
will allow PC's to directly write to the display (oh, by the way, this 
version will work on the PC *and* Unix systems this time).  It will be
about a month from now before I get the XWindows and the PC Graphics displays
written, since school is starting up and I will once again have access to
that kind of stuff.

If I get enough requests, I will release version 2.0 without the XWindows
and the PC Graphics displays.  Version 2.1 would then contain the missing
displays.  This version is a major major improvement over the previous
release... now has working Equates, Full expression evaluation, supports
the '86, '88 and Extended/Experimental Standards, supports the PCT and
XCH instructions, lots of command line options, etc. etc.  This version
also works great on a PC... including an old XT with 640k  (runs easily 
in 128k).  Oh, did I mention that this version is TWICE as fast as the 
previous version?   (Still twice as slow as KotH, but I am getting there.)

Well, anyway... send me EMail on the above PCT instruction and on whether
you want me to release the Deluxe package the way it is now... without
the graphical displays...

Thanks, and keep on programming!!! ;-)
