Bless you, Jacque!
I don't think there is such a property, but you can read the binary
file to see the format. If it starts with "REVO" then it is the new
format. But for what you are doing, I don't think you'll have to
resort to this.
Thanks to you it was simple for me to create a menuItem and general handler:
on CheckStackFormat
answer file "Select the stack."
if the result is empty then answer "Legacy Format ="&&(formatIsLegacy(it))
end CheckStackFormat
function formatIsLegacy stackPath
put false into legacyFormat
if there is a stack stackPath then
open file stackPath for binary read
read from file stackPath for 4
close file stackPath
if it is not "REVO" then put true into legacyFormat
end if
return legacyFormat
end formatIsLegacy
Go to preferences, "Files and memory" pane, and turn off the option
that automatically adds the ".rev" extension. Also turn on the
option in the same pane that preserves the stack file type when
saving a legacy stack.
Thanks.
I think a script would be the easiest way for the initial stack
creation. For a single file:
on mySave
set the stackfileversion to "2.4"
save this stack as <myFileName>
end mySave
Is there ever a need to reset stackFileVersion?

If the Rev preference is set to respect legacy stacks, you don't
need to run a script at all after the stack has been saved the first
time. Cmd-S will just work.
Cool!
