Query or set the internal variable that specifies the default options
for the save command, and defines the default format.
Typical values include "-ascii", "-text -zip".
The default value is -text.
When called from inside a function with the "local" option, the
variable is changed locally for the function and any subroutines it calls.
The original variable value is restored when exiting the function.
