Hello all,

I've been trying to construct a cool program as a visual like a screen saver in basic. I'm not very good at basic, but I'm having fun with it.

I was going for something that kinda looks like a display in movies like bladerunner, or outland. Those older late 80's sci-fi films.

I thought a listing of a running basic program would be a cool part to GOTO with a maze type program.

I wanted to get your thoughts on the way I listed a running program. My code snip doesn't include my entire program but I attached this snip to the end of my maze program to try and create a need look.


5 print "initializing...": dim k$(255): rp=41111
6 for t=124 to 255: w$="": rem --- fill the cache ---
7 b=peek(rp): w$=w$+chr$(b and 127): rp=rp+1
8 if b<128 goto 7
9 k$(t)=w$+" ": if rp < 41581 then next t
10 ad = 2049: print chr$(147)
20 nx = peek(ad) + 256 * peek(ad+1)
30 if nx = 0 then end
40 ln = peek(ad+2) + 256 * peek(ad+3)
50 print ln; " ";
60 for i = ad + 4 to nx - 2
70 c = peek(i): if c < 128 then print chr$(c);: goto 100
80 print k$(c);
100 next i: print: ad = nx: goto 20



The array is initialized with the rom key words to list the program running program.
If I had just put:

10 list
20 goto 10

it wouldn't work because list executes something like a run-stop first.

try it out.
