Help with Atari 7800 Basic

Recommended Posts

I'm trying to write a short user defined function in Atari 7800 Basic. I can't find any examples in the sample programs that come with it. The 7800 User Guide says you can and gives this example... It doesn't compile, I get this error message "ERROR, extraneous end statement found. I originally didn't indent the "end" but I tried to indent it and that didn't work.

What am I missing?

 

   function sgn
   rem this function returns the sign of a number
   rem if 0 to 127, it returns 1
   rem if -128 to 1 (or 128 to 255), it returns -1 (or 255)
   rem if 0, it returns 0
   if temp1=0 then return 0
   if temp1 <128 then return 1 else return 255
end

The documentation is incorrect - user-defined functions do not need an "end" statement.
