Assuming that exitLock is set to TRUE, nothing occurs automatically when the Control+period/

Q/W, Esc, or Command+period/Q/W keys are used. This handler checks keyboard input for keys

to exit and takes the user to a custom quit sequence:

on checkExit

if the commandDown and (the key = "." or the key = "q") and the exitLock =

TRUE then go to frame "quit sequence"

end

exit repeat

Syntax

exit repeat

Description

Keyword; instructs Lingo to leave a repeat loop and go to the statement following the end

repeat

statement but to remain within the current handler or method.

The exit repeat keyword is useful for breaking out of a repeat loop when a

specified condition—such as two values being equal or a variable being a certain value—exists.

Example

The following handler searches for the position of the first vowel in a string represented by the

variable

testString. As soon as the first vowel is found, the exit repeat command instructs

Lingo to leave the repeat loop and go to the statement

return i:

"on findVowel testString

repeat with i = 1 to testString.char[testString.char.count]

if ""aeiou"" contains testString.char[i] then exit repeat

end repeat

return i

end"
