Here are two tools I've found useful for the 48sx.  Included is also
one open question...

The first uses vectored enters to perform a nice `printerless printer'
interface: every operation is displayed in the status area.  For example,
6 ENTER 5 + 7 /  would first display 6 in the status area, then "5 +",
then "7 /".  I've found this real, real handy in a test/pressure situation
where I wanted to make sure I had just hit the right key.  With a litte
alteration, this can be turned into a trace mode for the printer.  

[sorry, no serial cable yet, I've done my best to make it easy on
those who have a cable]

\<< -62 -63 CF CF 'L' PURGE \>>



And now the question: the above, when confronted with a string that contains
a new-line, will DISPlay it in multi-line form.  But this is cumbersome, since
I would like to restrict output to a single line, perhaps terminating with
a "...".  In other words, I would like to display a string the way the oper-
ating system does when the string is in levels 2 or greater.  Any clues how
to do this?
