saving all open stacks in standalone

[Mark Swindell]

I want to save all the stacks that are open in a standalone.  These  
are separate stack files, not substacks.  What syntax needs to be  
changed to make the following work?

  if theKey is "Q" then
         put the stacks into saveUsAll
         repeat with x = 1 to the number of lines of saveUsAll
             save stack (line x of saveUsAll)
         end repeat
         quit
     end if


Thanks,
Mark
