Description

   Using the CLI$PRESENT and CLI$GET_VALUE routines, the UTIL$CQUAL_
   FILE_PARSE routine searches the command line for the qualifiers
   specified in the flags longword. When command line parsing
   finishes, UTIL$CQUAL_FILE_PARSE returns a pointer to the common
   file qualifier value in the context parameter.

   The context parameter must be used when calling either the
   UTIL$CQUAL_FILE_MATCH or UTIL$CQUAL_FILE_END routines. If a
   third parameter is specified, UTIL$CQUAL_FILE_PARSE returns a
   longword of flags indicating which qualifiers were found during
   the command line parse. The mask and field specifiers are listed
   in UTIL$CQUAL_FILE_PARSE Flags and Masks.
