SAVESHAPE is also capable of displaying a standard file open/save dialog box. In order to open a dialog box instead of a file, the file name contains a list of file type descriptors. A file type descriptor is a file type, optionally followed by an "=" and a description. The text "JPG=JPEG files" would be a vaild file type descriptor for all files ending with ".JPG". More than one file descriptor may be supplied; in this case, separate the descriptors with commas. The file open/save dialog would display all files ending with the given file type. A Windows dialog would also display the description of the file types, while a Macintosh dialog would display the matching files only. The Logo command SAVESHAPE "|JPG=JPEG files,BMP=Windows bitmaps| would, for example, display all files ending with .JPG or .BMP.

If you use "*" as a file type, the file open/save dialog displays all available files. This is done differently on Windows and the Macintosh. A Windows dialog would initially display all files with the first type, and offer all additional file types as choices. The Macintosh dialog would always display all files matching all file types.

If you provide an empty list, Logo automatically opens a file open/save dialog displaying all graphics images.

Clicking the Cancel button in a file open/save dialog cancels the execution of the SAVESHAPE command.
