Hi, if I want to split two string at ascii 0 ( <<"one",0:8, "two", 0:8>> ) then this worked: regexp:split(Str, "\x00") it gives : {ok, ["one","two",[]]} But I cannot get it to work with the new re module. It seems to insert \x00 between all the letters, it gives: ["o","n","e",[0],"t","w","o",[0],[]] am I overlooking something? Michael
