Your example code contradicts your statement. In your example code, colcheck() does not return a value from the function. That should not work and if it ran, that is a bug.

However, functions can return values but the caller is not required to retrieve the value returned by the function. It can ignore the return value.

Yes, sorry, I got interrupted while I was typing it in.

I tried

function colcheck() 
    fin = TRUE 
end function 
 
... some stuff 
colcheck() 
 
if fin = TRUE then exit() end if 

and the interpreter gave me an error.

when I changed

fin = TRUE 

to

fin = TRUE 
return fin 

The interpreter was happy.

I suspected nothing required you to actually assign the return value, but wasn't sure.

Thanks.
