To Set the Record Straight:
loman PM'ed me to point out he had not understood my original post because of problems with English. I will say here what I said to him in my reply.
I am also sorry that I did not recognize that English was the problem and recognize now that my earlier post was not that clear for a non-English speaking person.
Reversing is difficult enough when done in one's own language and it is much much harder when trying to learn it in someother language. I have great respect for those who try that difficult task and admiration for those who succeed. My apologies to loman for misunderstanding the problem.
Regards,
