Thanks! My script seems to work with dclone. Though the (deep) recursion takes a lot of time ... What is your opinion, would it pay off (in performance) when I rewrite the script in such a way that I do not use dclone, but string manipulation routines instead? So: - passing a single dimension array containing 16 elements with 16-character strings and doing substr() - instead of passing a 2 dimensional (16x16) array passing 1-character strings and doing dclone Every pass I only change a single character, then I run some tests and so on.
