Sorry cuitesun, I did not mean to offend anyone. Just trying to keep our PicBasic forum on topic. We could start to (try) to discus C, C++, Fortran, Java. And I am sure some of our members are well versed on other topics as well. But that really was not what this site is intended for. That is why we suggest going to a site whose members specialize in the subject of your inquiry.
