exit repeat

exit to HyperCard
The exit keyword interrupts the current flow of control.
Exit repeat sends control to the end of a repeat structure, ending execution of the loop regardless of the state of the controlling conditions.
The exit functionName and exit messageName forms stop the current message or function handler. Control returns to any pending statements from another handler, if any.
Exit to HyperCard terminates all running or pending handlers and cancels all pending messages.
Using exit to leave a function handler sets the value of the function to empty.
Examples
if N = 0 then exit repeat
if it is empty then exit mySave
if there is no card field "Index" then exit indexFunction
-- In the following example, the openCard message will not occur as the
-- user goes from card to card:
on closeCard
flash
exit to HyperCard
end closeCard
on openCard
beep
end openCard
-- The newButton message will occur because HyperCard sends it before
-- the exit to HyperCard:
on anExample
doMenu "New Button" -- creates a new button, sends newButton message
exit to HyperCard
end anExample
on newButton
beep
end newButton
