cDEC$ ALIAS

  Specifies an alternate external name to be used when referring to
  external subprograms.  It takes the following form:

  cDEC$ ALIAS internal-name, external name

    c               Is one of the following: C (or c), !, or *.

    internal-name   Is the name of the subprogram as used
                    in the current program unit.

    external name   Is a name, or a character constant delimited
                    by quotation marks or apostrophes.

  If a name is specified, the name (in uppercase) is used as the
  external name for the specified "internal-name".  If a character
  constant is specified, it is used as is; the string is not changed
  to uppercase nor are blanks removed.

  The ALIAS directive affects only the external name used for
  references to the specified "internal-name".

  Names that are not acceptable to the linker will cause link-time
  errors.

  This directive can be useful when compiling applications written
  for other platforms that have different naming conventions.
