[Coco] Returning a string to basic ?

[Bob Devries]

Phill,

thinking more on that....

You could have the user create a suitable sized string variable, then use 
VARPTR to find out where it is, and using INTCNV to pass the address to your 
code. Your code can then write to the string memory, and perhaps signal the 
user programme by sending a value using GIVABF.

Sorry, my BASIC/assembler is a bit rusty, since I'm almost totally OS9 now.

Another $0.02 + GST
