Replying to mcgovern@handel.cs.colostate.edu and giovin@ecs.umass.edu
concerning how to get Mousetext characters on the text screen using BASIC.

To get Mousetext characters, you must have the enhanced video feature.
Probably the IIgs would have it, my IIc+ has it.  The feature must be
activated by some sort of PR# command (PR#3 in my case since the 80-
character card is hooked up to theoretical slot 3.)  Once enhanced video
is on, use the PRINT CHR$(27) to turn on mousetext.  At that point, the
inverse of the characters A through Z and @,[,\,],^, and _ would be
in mousetext.  To show the mousetext, use INVERSE or PRINT CHR$(15)
(The CHR$(15) works with the enhanced video only.).  To turn off mousetext,
set video back to normal through NORMAL or PRINT CHR$(14), then turn off
the mousetext set by using PRINT CHR$(24).

REMEMBER, YOU MUST BE IN ENHANCED VIDEO MODE TO PRINT MOUSETEXT ON THE
SCREEN!!!  To deactivate enhanced video, use PRINT CHR$(21).

Other calls that are useful in enhanced video include:

     PRINT CHR$(17) to set line width to normal 40 characters per line
          while using enhanced video.
     PRINT CHR$(18) to set line width back to 80 characters (default for
          enhanced video)

I got this information from _Apple IIc User's Guide_ which might be
available in libraries (It is here at Iowa State!)

Hope this helps!!!
