H100 Programs in GWBASIC/BASICA
Some of these programs were developed on the H100 in GWBASIC, then were
modified for PC compatible BASICA, and then were re-edited to restore to GWBASIC
compatibility. If you find any remaining SCREEN 12 statements (or any other
BASICA statements) that are still enabled, they should be REMmed out for H100
use.
Programs
Programs that create graphics or generate graphics files
- AUTORAND.BAS
- Continuously generates random IFS variables and displays the associated
fractal images.
A second version of the program runs faster but has fewer features. A
third reads an .IFS file and generates its image. This page also links
to a brief overview of IFS fractal generation and to programs that convert
from rectangular coordinates to polar and back.
-
- BIFURCAT.BAS
- Shows Robert May's logistic map bifurcation diagram, as described in
Chaos:
Making A New Science, by James Gleick.
-
- DLA3.BAS
- Simulates diffusion limited aggregation. Particle randomly wanders
around the screen. When it collides with boundary, it sticks, creating tree
or fern-like structures.
-
- HENON.BAS
- Produces graphic image of the strange attractor of Henon, regarding
chaos.
-
- CHAOSGAM.BAS
- Uses a random walk to generate areas with fractal boundaries. A second
program draws a donut shape.
-
- ATTRACT.BAS
- Strange attractor? Probably not, but a waveform appears on the screen.
-
- NORMAL.BAS
- Builds a normal distribution at the bottom of the screen (the dropped
marbles also show their trails as they fall), but has the "sticky" routines
from DLA, so it makes strange treelike formations at the screen bottom,
instead, in a vaguely normal distribution.
-
- PARABOLA.BAS
- Graphic display of equation instability. The later iterations create a parabola shape.
-
Programs that transform or manipulate graphics files.
- AUDISPIC.BAS
- Two programs to display .PIC files that were saved by AUTORAND.BAS or
other programs. One displays a single file; the other automatically displays
consecutively-numbered .PIC files.
-
Misc. other programs
- AUTOHIRE.BAS
- Plots points from data files to an on-screen graph in graphics mode, 640 x 225.
-
- KOCHMATH.BAS
- Does a calculation associated with the Koch curve (snowflake). All it
really does it print some lines of numbers, but those numbers show that the
fractional dimension of the curve is the limit towards which the increased
area goes.
-
-
Print mailing labels
- Two trivial BASIC programs to print mailing labels.
