  Syntax:   OPTION CASEMAP:maptype
 
  See also: /C<x>
 
  Description:
 
     Controls the mapping of characters to uppercase. The <maptype>
     parameter can be ALL, NONE, or NOTPUBLIC, which correspond to the
     /Cu, /Cp, and /Cx command-line options. You can use this option
     only once per source file. The current language type, if any, will
     override <maptype>.
     See: Language Type
 
     CASEMAP:NOTPUBLIC is the default. The CASEMAP option is set to ALL
     with the M510 option.
