[Coco] OS-9 History

[Bill Pierce]

Frank, if I remember right, you had to save the Basic program in Ascii, then use an OS9 text editor and save before loading into Basic09. There will be more errors than imaginable, but Basic09 mkarks them for easy editing.
I remember moving several simple Basic files to Basic09 back in the 80s. The biggest thing is the Data structure. Basic allowed you to introduce variables at any time just by using them. In Basic09, you had to declare all variables. I would always go through the prorgam and fix all the variables. It eventually became a habit in Basic to declare my variables early as a habit because of my work in Basic09.

You may find this summary of OS9 print ads interesting or informative :

Very informative indeed, Aaron! That's a nice compilation of OS-9 ads and 
information. I never knew that one could program in BASIC09 with a line number 
structure just like DECB! If I'd known that I may have tried to port a couple 
BASIC programs I'd written years a go to BASIC09. Would have been neat to run 
them under OS-9, and not too hard to port using the same structure.
