arrays..how to question.

Joe M

I need a little basic help(hah!)...

So If I want to define an array and then loop through it, is that possible in pbasic?
i.e.
foo=[noparse][[/noparse]"cat","dog","bird","fish"]
for loop = 1 to 4
debug "foo[noparse][[/noparse]loop]",cr
next

Which leads into my next question, can you reverse and array, or loop through it backwards?


thanks!

Joe,

·· You are attempting to create an array with string variables which is not a supported variable type on the BASIC Stamps.· You can create an array of bytes and index it within a loop, but not the way you are showing.· What are you trying to accomplish, perhaps there is an easier way.

Thanks, this is what I want to do, I have 16 leds hooked up to my stamp, and I wanted to use OUTS and turn them on and off.

So... I'd like to set something/a variable to hold values like "111111000000", "11111100000", "111111110000"... and then loop through it with OUTS = %variable[noparse][[/noparse]x]

Does that sound possible or am I totally off base?

Thanks,
-Joe

PBASIC has a command called LOOKUP that will do what you want it to do. You can also READ elements from a DATA table.
