JUMP -- Moves between commands in an action-list.


FORMAT

  Jump label



REQUIRED ARGUMENT

  label          A command label.  The label must appear within the same
                 command string.  A label is an identifier consisting of one
                 or more alphanumeric characters followed by a colon (:).
                 The first character in a label must be a letter; it cannot
                 be a digit.


OPTIONAL ARGUMENTS

  None.


DESCRIPTION

  You can only use JUMP within an action-list.  JUMP works like a goto
  statement.  Use JUMP to go from one portion of an action-list to another.

  In the action-list, you can specify the label before or after the
  corresponding JUMP command. That is, you can jump forward or backward.

  DEBUG looks for the label using a simple string matching search.  Therefore,
  be careful that you do not pick a label which conflicts with another part of
  the line.  If you have a program variable called label, for example, a line
  like the following would loop incorrectly:

     _ [SET label:= 5;
     _      label: PRINT 'Want loop here';
     _      JUMP label]

  DEBUG would jump to the first "label:", rather than the second.

  Reference manual.
