default_filename - The procedure accepts a default filename that will be
used in the filename prompt. This parameter is of
type STRING and can be blank.
An invalid parameter, for example, calling the
procedure with a date, will cause an error message to
be displayed and a zero length string to be returned.
R e t u r n s
This procedure returns a variable of type STRING.
The return value is a nickname:filename string. The file extension
will not be returned, so that a user can enter a index file (.IF) and
the true database name would be returned.
