XOR operator in tablemaker

[Danielle et jean Thierry-Mieg]

the problem is that if %7 contains a space it does not parse correectly
it is not really beacuse of XOR

%7 = "K 560"

will evaluate after replacement to
 K 560 = "K 560"

possibly this is the problem
may be
  "%7" == "K 560"
would work
but i do need to test that and the similar thing in AQL
