I suppose if we want to be economical, just one byte would do...
function isLegacy someStackFile
open file someStackFile for read
read from file someStackFile for 1
close file someStackFile
return (it is "#")
end isLegacy

You only need to read the first couple of bytes - in a 'legacy
stack' the first 2 bytes will be '#!', whereas in a newer stack
they will be "RE".

Yes, as I already posted yesterday :-)
OK, I suggested to check the first EIGHT bytes... ;-)
