[edit] Example
Program input_test; Begin While( !key(_esc) ) delete_text(ALL_TEXT); if( key(_left) && !key(_right) ) write(0,160,120,4, "LEFT"); end; if( key(_right) && !key(_left) ) write(0,160,120,4, "RIGHT"); end; frame; End; exit(); End

This will output the words LEFT or RIGHT according to the keys you press, or it will quit the program once ESCAPE is pressed.
