i just compared the output with PRINT s and i saw the same result. i was wrong because i did not know about string manipulation in c. i did not understand the zero terminated string you mentioned in help.
i found some info at this page http://www.dfstermole.net/OAC/hstrings.html Is there any way to produce a zero terminated string in Gambas to demostrate the StrPtr()?
