# 3B068h SYSEVAL runs the Matrix Writer (new, empty matrix).
If you want to pre-load it with an existing matrix, place the matrix
on level 1 and use # 3A645h SYSEVAL.

All the "non-programmable" key functions are really programmable, of
course, by SYSEVALing the proper address.  For example, the inter-
active stack can be programmed by # 3A93Dh SYSEVAL.

INPUT lets you turn alpha mode on, but PROMPT doesn't, unless you use
# 3AA0Ah SYSEVAL first.  Note: flag -60 is used by the alpha key, and
hence by this SYSEVAL, which _is_ the alpha key's program.

Want to program VISIT?   Dumb Visit (key 52.3) is # 3B12Bh SYSEVAL;
Smart Visit (key 35.3) is # 3AF69h SYSEVAL.  Keep in mind that the
action of keys depends on the mode you're in; "smart visit"
becomes "full down" in graphics mode...

These work on version E.  All were found using the Voyager program
by Derek Nickel.  Use them at your own risk.
