[Coco] Extended basic 1.1 command?

[Bill Pierce]

Charlie,
You have to use PEEKs in CB & CEB for the firebuttons.
"BUT=PEEK(&HFF00) OR &H80"
"IF BUT=&HFF"  = no button
"IF BUT = &HFE" = right button
"IF BUT = &HFD" = left button

I think that's right,
Hope it helps

Subject: [Coco] Extended basic 1.1 command?


I am trying to edit one of my old programs written on the Coco3 to run on my 
Coco1.

The program reads

120 IF BUTTON(0)=1 THEN 140
130 GOTO120

This detects if Joystick 0 button is pressed, if so goto 140...

I see that BUTTON is not a valid command in Extended Basic 1.1 in my coco1.

Can someone give me a simple example how to do the equal of these two program 
lines in the older Extended Basic?

Thanks.

Charlie
