> gwbasic had a function to relabel all the lines. And the labels skip by 10 numbers exactly for the purpose of inserting lines. Then when you had hit the limit you'd ask the computer to relabel them in steps of 10 again. gw-basic was released c4 years after this book, and there was a huge change over that period: 1976 - Release of Apple I 1977 - Release of Apple II / Commodore PET 1979 - This book 1982 - Commedore 64 1983 - GW Basic This book is pretty much closer to the Apple I than gw-basic. Perhaps I should have specifically said developing basic in 1979 though as referenced in that book though (and there isn't just one sort of basic - there are so many dialects).
