Goofy question #7234

[Richmond Mathewson]

I am obviously missing something . . .

. . . so badly so that I've been trawling Danny Goodman's "Complete" HC 
2 . . .

and NOT getting 'it' . . .

SO: one can set up a custom command:

on GoRed
   set the backGroundColor of card 1 to red
end GoRed

and one can call it:

on mouseUp
    do GoRed
end mouseUp

and one can set up a custom function:

function GoRed
   set the backGroundColor of card 1 to red
end function

Now: is the reason I cannot call that function because it takes NO 
parameters?

Richmond.
