How do I read an integer from the keyboard ?
I want to replace N = 4, by something like N = toInteger(stdio::readLine()),
but I get TaskWindow\TaskWindow.pro(40,14) error c229: Undeclared identifier 'toInteger/1->'
with N = math::toInteger(stdio::readLine()),
I want in the onShow( ) clause of a window to read an integer from the keyboard if possible and show it with stdio::write(N). I can dsiplay data with stdio::write(N) in the windows drawing area no problem. It must not be in the onShow( ) clause I can add a menu item and call some code instead.
Code: Select all
Exception: noStream (com/visual-prolog/stream/stream_exception) The predicate has no stream assigned Predicate name = stdio::readLine
Thank you, bye.
