Hi Pavel,
Good idea. I have finished but I'll change it to this way soon and test it in next some days.
What the idea about the character to indicate stop?
I mean this patten maybe indicate just once maybe indicate repeatedly until the next patten.
What about "/"? If there is a "/" at end then stop it else repeat it?
Thanks.
Joe
