WAIT

Description:

This simple statement causes program execution to stop and wait for user input events. When the user interacts with a window or other control owned by the program and generates an event, program execution resumes at the event handler appropriate for their interaction.

Usage:

'demonstrate the wait command (in three places)

nomainwin

open "Geometric wite-board" for graphics_nsb as #geo

print #geo, "trapclose [quit]"

print #geo, "when rightButtonUp [popupMenu]"

wait ' stop and wait for a menu item to be chosen

[popupMenu]

popupmenu "&Square Spiral", [asSquare], "&Triangular Spiral", [asTriangle]

wait

[asSquare]

print #geo, "cls ; home ; down ; color red"

for x = 1 to 120

print #geo, "go "; x; " ; turn 87"

next x

wait

[asTriangle]

print #geo, "cls ; home ; down ; color blue"

for x = 1 to 120

print #geo, "go "; x; " ; turn 117"

next x

wait

[quit]

close #geo

end

Note: In general, Liberty BASIC encourages the use of wait over the previous practice of using input.
