   EXIT PROCEDURE WITH value IF expression

The EXIT PROCEDURE WITH…IF command is used to stop execution of a specific function, and transfer control of the program to the first statement following the calling of that procedure, giving back a value in case an expression is true.TRUE

The command is useful to exit when an error or unexpected condition occurs, and it can be used to end the procedure and handle the error appropriately. In some cases, using EXIT PROCEDURE WITH…IF can make your code more efficient by avoiding executing unnecessary statements. EXIT PROCEDURE WITH…IF allows you to create more complex control flows and make dynamic decisions during program execution. Excessive use of EXIT PROCEDURE WITH…IF, however, can make your code more difficult to read and maintain.

  PROCEDURE test[ x AS INTEGER ]
     EXIT PROCEDURE WITH 0 IF x > 10
     PRINT "X is less or equal to 10"
     RETURN 1
  END PROC
