Hi guys,

I added the TRIS definitions, but no go. Also, although a pin like CP is referred to as the 'Input clock pulse', it remains an output pin since the PIC is sending this signal to the 74HC166. But no matter, that's not the problem either.

I also put the [LOOP] back in when comparing the individual bits to %1, I lost that along the way with the multitude of changes, not that either.

I've come up with an alternative method of achieving my goals. The other thread discussing QBASIC has given me an idea that could greatly improve my design, making it more flexible, less complicated and much more user-friendly. I'll explore that for a while and fall back on this if the other option doesn't pan out.

Having graduated from Champlain College in 1983 in Data Processing, some water has flowed under the bridge since the last time I've used QBASIC. I've been a mainframe programmer using COBOL since then.

Merci!

Robert
