Case_Preservation_and_$FILE

   DCL attempts to preserve the casing of file specifications. It
   can do this only for commands defined with the Command Definition
   Utility (CDU). DCL preserves case for any item defined in the
   command definition file (.CLD) with the $FILE parse type.

   Refer to the Command Definition Utility manual for more
   information.
