In reference to all the messages about the origins of BCPL ..... fine. Thank you. Most informative. But...... What the heck is a BPTR and how should it be used (ie when converting from a normal APTR), and WHY is it used in AmigaDOS? Is it a normal pointer, long word aligned, shifted right by 2? Why by 2 (assumming the BCPL langauge knows only of word data types)? It would seem the LS Bit (bit 0) is the Word/Byte selector. Why long word aligned? If I've made silly mistakes please feel free to flame. Thanks for the help. Oh yes.... Bob Peck, I haven't forgot about that letter I was going to scribble off. It's just I got my V1.1 kit a couple of days age and have been virtually in a catatonic reading state ever since! So far the 1.1 RKManuals seem like winners. -- Jeff Gortatowsky {allegra,seismo}!rochester!ritcv!husky!jdg Eastman Kodak Company <Kodak won't be responsible for the above comments, only those below>
