Hi Alain,

Thanks for your input, always good information from you.

I will do as you suggest and see what I get but I have quite a few other asm programs I've been storing for future use/ideas which would take a great deal of time and effort to convert to PBP... So I still want to know the answer to the original question - for this reason I attached the smallest of my asm listings so the task would not be too daunting for assistance.

I agree there is a lot to be learnt from doing what you suggest and examining the result - anything else you can offer will be welcome.

Kind regards,
Bill
