Raja,

Like Chris, I couldn't quite understand your question, but Dennis' answer is a good one to what I think you might have been asking.

So, assuming that we are on the right track here, are you asking purely out of interest or do you have a big performance and/or code-size issue?

If you have a real problem with code size, then you can avoid the return-value (and parameter-passing) overhead by using Global Variables
But BEWARE: extensive & undisciplined use of globals can be a real debugging & maintenance nightmare...!!
