GOTO Statement
 ----------------------------------------------------------------------------


 Action

 Branches unconditionally to the specified line.


 Syntax

  GOTO { linelabel |  linenumber}


 Remarks

 The argument  linelabel or  linenumber indicates the line to execute next.
 This line must be at the same level of the program. The  GOTO statement
 provides a means for branching unconditionally to another line ( linelabel
 or  linenumber). A  GOTO statement can branch only to another statement at
 the same level within a program. You cannot use  GOTO to enter or exit a
 SUB or  FUNCTION procedure or multiline  DEF FN function. You can, however,
 use  GOTO to control program flow within any of these program structures.

 It is good programming practice to use structured control statements ( DO...
 LOOP,  FOR... NEXT,  IF... THEN... ELSE,  SELECT CASE) instead of  GOTO
 statements, because a program with many  GOTO statements can be difficult to
 read and debug.


 Example

 The following example calculates the area of a circle. The program uses the
 GOTO statement to repeat the operation.

 CLS      ' Clear screen.
 PRINT "Input 0 to end."
 Start.
    INPUT R
    IF R = 0 THEN
      END
    ELSE
       A = 3.14 * R ^ 2
       PRINT "Area ="; A
    END IF
 GOTO Start

 Output

 Input 0 to end.
 ? 5
 Area = 78.5
 ? 0
