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.
