      __Dir( [<cFileMask>] ) --> NIL
   $ARGUMENTS$
      <cFileMask> File mask to include in the function return. It could
      contain path and standard wildcard characters as supported by your
      OS (like * and ?). If <cFileMask> contains no path, then SET DEFAULT
      path is used to display files in the mask.
   $RETURNS$
      __Dir() always returns NIL.
   $DESCRIPTION$
      If no <cFileMask> is given, __Dir() displays information about all
      *.dbf in the SET DEFAULT path. This information contains: file name,
      number of records, last update date and the size of each file.

      If <cFileMask> is given, __Dir() list all files that match the mask
      with the following details: Name, Extension, Size, Date.

      DIR command is preprocessed into __Dir() function during compile
      time.

      __Dir() is a compatibility function, it is superseded by Directory()
      which return all the information in a multidimensional array.

      If long file names are available Harbour will use/display the first
      15 characters else Harbour will use/display a 8.3 file name consistent
      with CA-Cl*pper.
   $EXAMPLES$
      __Dir()      // information for all DBF files in current directory

      __Dir( "*.dbf" )         // list all DBF file in current directory

      // list all PRG files in Harbour Run-Time library

      Fill pre-defined arrays with file/directory information

      ADir( [<cFileMask>], [<aName>], [<aSize>], [<aDate>],
            [<aTime>], [<aAttr>] ) --> nDirEntries
   $ARGUMENTS$
      <cFileMask> File mask to include in the function return. It could
      contain path and standard wildcard characters as supported by your
      OS (like * and ?). If you omit <cFileMask> or if <cFileMask> contains
      no path, then the path from SET DEFAULT is used.

      <aName> Array to fill with file name of files that meet <cFileMask>.
      Each element is a Character string and include the file name and
      extension without the path. The name is the long file name as
      reported by the OS and not necessarily the 8.3 uppercase name.

      <aSize> Array to fill with file size of files that meet <cFileMask>.
      Each element is a Numeric integer for the file size in Bytes.
      Directories are always zero in size.

      <aDate> Array to fill with file last modification date of files that
      meet <cFileMask>. Each element is of type Date.

      <aTime> Array to fill with file last modification time of files that
      meet <cFileMask>. Each element is a Character string in the format
      HH:mm:ss.

      <aAttr> Array to fill with attribute of files that meet <cFileMask>.
      Each element is a Character string, see Directory() for information
      about attribute values. If you pass array to <aAttr>, the function
      is going to return files with normal, hidden, system and directory
      attributes. If <aAttr> is not specified or with type other than
      Array, only files with normal attribute would return.
   $RETURNS$
      ADir() return the number of file entries that meet <cFileMask>
   $DESCRIPTION$
      ADir() return the number of files and/or directories that match
      a specified skeleton, it also fill a series of given arrays with
      the name, size, date, time and attribute of those files. The passed
      arrays should pre-initialized to the proper size, see example below.
      In order to include hidden, system or directories <aAttr> must be
      specified.

      ADir() is a compatibility function, it is superseded by Directory()
      which returns all the information in a multidimensional array.
   $EXAMPLES$
      LOCAL aName, aSize, aDate, aTime, aAttr, tmp
      LOCAL nLen := ADir( "*.dbf" )  // Number of JPG files in this directory
      IF nLen > 0

         aSize := Array( nLen )
