This program shows you your biorythms for 24 hours or 24 days. It shows physical,emotional & mental condition. This group contain 3 programs b1,b2,BTI and 3 pictures b1,b2,b3. To run this program start 'b1' on your TI. If you want to make it faster and save more memory delete folowing programs from TI: 'BTI' and pictures 'b1','b2' and in program 'b1' delete 9th line (BTI). That's all about using this program. I think it's clear. If you have some questions, good ideas or problems contact somebody of us by e-mail at address: martinko@decef.elf.stuba.sk or velcicky@decef.elf.stuba.sk
