VMS Help PASCAL, Statements, BREAK *Conan The Librarian (sorry for the slow response - running on an old VAX) |
The BREAK statement immediately transfers control to the first statement past the end of the FOR, WHILE, or REPEAT statement that contains the BREAK statement. The BREAK statement appears as a single word: BREAK is equivalent to a GOTO to a label placed just past the end of the closest FOR, WHILE, or REPEAT statement. Use caution when using the BREAK statement because future additions to the code may result in the BREAK statement leaving a different loop than was originally intended. The following example shows the usage of the BREAK statement. name := GetInput('Your name?'); IF ExitKeyPressed THEN BREAK; address := GetInput('Your address?'); IF ExitKeyPressed THEN BREAK; Person[Num].Name := name; Person[Num].Addr := address; Num := SUCC(Num); UNTIL Num > 50; In the example, a user-defined function GetInput interacts with the user and sets a global Boolean variable ExitKeyPressed if the user presses an Exit key. The BREAK statement exits the loop here, without storing data in the array.
