LVSEARCH  String CS|CI First|Next

  Search the LV for "String"

  CS|CI means = Case Sensitive (CS) or Case Insensitive (CI) 

  First|next are for control :

    LVSearch "MyString" cs first 
    - will return with the first line containing "MyString". 

      You can get the line number, text etc of the line found, 
      via the  Listview internal variables  

      You can get the position of the string within the line
      via the  Search internal variables 

  You can thereafter call :

    LVSearch "MyString" CS next
    - again and again, to get the rest of the lines or strings.

  If there are 2 or more occurences of the same string in the
  same line, LVSearch will stop as many times as there are 
  strings for. (This has been added in version 3.6+)

  When there are no more more lines containing the given text, 
  then the $$lv.line internal variable will contain "" (nothing)
  and that's how you know you're finished.

  Note : "" is *not* the same as 0 in Gui4Cli.
         "" means Nothing - 0 means the top line.
