I have develop an app that is communicating with a modem and is parsing large strings coming from modem the problem is that as the app continue to parse strings the memory that the program is 'eating' grows enormously with result 'memory overflow' .So i though clearing those strings. Easy to do cuase the modem is sending strings only when is ringing so i though by clearing the string just b4 modem ring should clear the memory too but it doesn't . Any ideas?

thnks

ps: i have already used a concat class for appending parsed strings to vars
