What's wrong with this code?

Velvet Leopard

Hewwo, all.· I wrote this code to make a little song to cheer up my little bro.· I followed the steps in my "What's a Microcontroller" kit, but no go.· After the 16th cycle of the (for next) loop, it repeats from the beginning and it never stops despite the (end) command.· My kit did not come with a Basic Stamp II User's Manual.· Where can I get the manual?

Your index variable is a nib which is 4 bits and can only hold up to 15. You need to change it to a byte.

Yes the programmign manual is avaliable for download click to download

Like an idiot I downloaded and printed the WHOLE manual then the next day I bought a boe-bot kit which contained that manual, what a waste of ~200 sheets of paper and nearly half of a $30+ ink catridge.
