Hi Giccomo Try myMessage = StringJoin @@ Map[ToString[TraditionalForm[#]] &, exprs] or if you want to have each expression on a separate line myMessage = StringJoin @@ Map[ToString[TraditionalForm[#]] <> "\n" &, exprs] I used for testing exprs = {8, "hello", x^4, Integrate[x^3, {x, a, b}]} Best Regards Norbert Marxer www.mec.li Giacomo Ciani wrote: > I have several expressions I whant to convert to string and then > concatenate togheter to create a message to be sent to the standard > output and written on a text log file.
