PASCAL, Statements, GOTO

 *Conan The Librarian (sorry for the slow response - running on an old VAX)

  The GOTO statement causes an unconditional branch to a statement
  prefixed by a label.

  Syntax:

     GOTO label

  The 'label' is an unsigned decimal integer or symbolic name that
  represents a statement label.

  The GOTO statement  must  be  within  the  scope  of  the  label
  declaration.   A  GOTO  statement  that  is outside a structured
  statement  cannot  jump  to  a  label  within  that   structured
  statement.   A  GOTO  statement within a routine can branch to a
  labeled statement in an enclosing  block  only  if  the  labeled
  statement appears in the block's outermost level.

     FOR i := 1 TO 10 DO
        BEGIN
        IF Real_Array[i] = 0.0
        THEN
           BEGIN
           Result := 0.0;
           GOTO 10;
           END;
        Result := Result + 1.0/Real_Array[i];
        END;

     10: Invertsum := Result;

  This example shows how to use a GOTO statement to  exit  from  a
  loop.   The  loop  computes  the  sum  of  the  inverses  of the
  components of the variable 'Real_Array'.  If the value of one of
  the  components  is  0.0,  the  sum  is  set to 0.0 and the GOTO
  statement forces an exit from the loop.
