These call-back functions operate on a %eb edit box in same same manner as
EDIT_FILE_OPEN. If an edit box has not been filled using EDIT_FILE_OPEN,
EDIT_FILE_SAVE operates like EDIT_FILE_SAVE_AS and displays the standard 'file
save' dialog. Each call-back takes two character string arguments: one for the
file pattern and the other for the resultant file name (see EDIT_FILE_OPEN
above). The contents of the edit box are written to the file but the edit box
is not closed. An example program appears in A
simple text editor.
