                             FILEDISP Mask Options

1) The item type returned is the "highest level" field which is nonblank.
   For example, if FILE is left blank, a list of libraries will be returned;
    if both FILE and LIBRARY are blank, the list will be of volume names.
2) Special characters "?" and "*" may be used in addition to standard
    characters to search for "generic" file/library/volume names; the
    field characters are interpreted as follows:
         "?" - this accepts any string, including a null.
               e.g., "#?PRT" would accept #PRT,#XYZPRT, etc.
                     "?" alone would accept all file/library/volume names
         "*" - this accepts any single nonblank character.
               e.g. "FRED*" would accept FRED1 but not FRED or FRED12
         " " - blanks are ignored wherever they appear in the field
   All other characters are handled as usual; wherever they appear in the
    mask field, they must also appear in the file/library/volume name.
