Very well expained.

I posted this here by miskate and deleted it straight away so not sure how you come to see it unless the system was to quick for me and emailed you instantly.

I played with just using byte0 & Byte1 and got the correct answer but couldn't understand how it worked.
I did a search of the lst and could find nothing which expalined that it's recombines the values.
Likewise my PBP manual & the online version yielded very little.
