    thanks!

    the idea was to start from an empty string, then add the chars to the string to a given position. I iterate from A to Z and use the strange string on top. this string is splitted using the \W. so looking at the start: "14-(5+(248" that will be splitted in ("14", ,"5", ,"248"). so the control data for the A is "14", nothing for B, then "5" for C and so on. the "14" is splitted again and i used the value in hex (this is important, for the "b" code later on), so i'll get 1 and 4, and then the string is updated inserting A in 1 and 4. the ending string is as expected JAPH. to keep the code small i was not able to use anything more then hex data, but a "r" was too far (more then 0xf) so i had to start with it in the string, as for the spaces.
