[ The Sun version in the original posting needed a graphics library
developed at Lucasfilm; here's something more useful. --r$ ]
This file contains instructions for creating a version of Logo to run
under Suntools. You need four new files which follow below: sun.i,
logo.c, logo.icon and Makefile. The following changes must be made to
the logo source as well. I believe the line numbers refer to version 4
source but hopefully with the context given for each change it won't
matter. "Make" will produce two binaries: logo and logotool. When
running logo under suntools use logotool instead of logo (logotool
actually creates a window and then forks logo to run in it; logotool
then handles repaint requests for the tool).
Note: the routines in sun.i currently only support monochrome graphics
(although it would not be difficult to add color). I made these
changes several years ago and I haven't devoted any time to the code
since then, but they still compile under any version of SunOS from 1.0
on (that's when SunWindows was introduced).

XThe first two changes add the commands fill and textsize. Fill fills in the
Xregion around the current position of the turtle using the current pen color.
XThe boundary of the fill can be an arbitrary shape (for instance:
X"repeat 4 [fd 100 rt 90] rt 45 fd 10 fill" produces a black square). If the
Xboundary has "holes", the whole screen may get filled. Textsize takes one
Xargument which is the number of lines you want the text window to be in split
Xmode.
