Syntax:  PATTERN SEARCH pattern_search_string noundo

  Enables the use of wildcard patterns in a search string and searches
  the current buffer for all occurrences of that string.

  This command enables the special interpretation of wildcard patterns
  in a search string.  LSE ignores any occurrence of the search string
  that begins at the current cursor position and displays a message if
  the the string cannot be found.  Use the SET SEARCH PATTERN command
  to specify the style of wildcard patterns (VMS, ULTRIX or TPU).

  For the TPU pattern style the pattern_search_string is a TPU
  expression which must evaluate to a TPU pattern (for example:  "'abc'
  | 'def'").

  For details of the pattern styles use the command HELP PATTERNS.
