Instructions:
With the provided ATR disk image, boot to BASIC, type ENTER "D:STAR.LST" to
load the program, and type RUN.
Description:
This program uses the function:
U = ABS(Y)
V = ABS(X)
S = (U>4) AND (V>4) OR (ABS(U-V)>4)
This is calculated for each point in the X and Y ranges from -8 to 8, drawing
a space or a star character.
Comments:
To minimize size, this program asumes the screen is 38 columns, calculating
the function for all columns and avoiding to print new-lines.
Atari BASIC is slow at calculations, so the program takes a while to print
the full star.
