TREE&FOX: Preliminary program notes
N.B. For detailed documentation see TREE&FOX.DOC.
Welcome, and thank you for your interest. Please note that all the
programs included are exploratory prototypes, and that the author
makes no warranties of any kind as to their robustness or suitability
for any application.
A. TREES.ICN
1. Translate and run as usual; the program should work with
most versions of ICON.
2. Input is expected from a text file called TREES.IN. A
sample file has been provided.
3. Note that TREES calls for a non-proportional font and
relies on the pseudographics characters of the extended
IBM-ASCII set.
B. TREECAD.ICN
1. This program is heavily dependent on DOS calls and video
routines. It runs under ordinary (non-386) DOS ICON from
version 8.0.
2. TREECAD makes nonessential use of SCROLLER.EXE which expects a
text file called TREECAD.IN.
3. For a Windows installation of TREECAD see TREE&FOX.DOC, para 2.4.
C. FOX.ICN
1. FOX makes a few DOS calls so that it, too, must be run from
an ordinary (non-386) DOS version of ICON. (The routines
involved are largely nonessential so that porting to a different
environment should be feasible.)
2. FOX expects the lexicon file FOX-LEX to reside in the
current directory.
3. FOX makes nonessential use of SCROLLER.EXE which expects a
text file called FOX.IN.
4. For a Windows installation of FOX see TREE&FOX.DOC, para 3.2.
