01  opensave-data.
    03 opnsav-filename       pic x(256).
    03 opnsav-flags          pic 9(4) comp-x value 0.

    03 opnsav-title          pic x(80).
    03 opnsav-filters        pic x(512).
    03 opnsav-default-filter pic 9(4) comp-x value 0.
    03 opnsav-default-dir    pic x(128).
    03 opnsav-basename       pic x(128).

opnsav-default-ext
This item holds the default file name extension. The extension is the string of characters that appear after the "." in the file name.

Set this item to spaces to avoid having a default extension.
 
opnsav-title
String to be placed in the title bar of the dialog box. If this member is spaces, the system uses the default title.

opnsav-default-dir
Specifies the initial directory.
