Hi Monks! Thanks for your questions. Please find the answers below. A macro to do what? -I want macro do following activity - To check whether the variable are define before using - Log the value passed to the variable entering/leaving a function i.e. to printing the trail of Input and output variable. - Memory statistic before entering and leaving the function to have idea about the memory status. I don't want that code to be part of the final product. I need those things for development/debugging purpose. What are your inputs? Input is .pl file What processing do you need to do? - To check whether the variable are define before using - Log the value passed to the variable entering/leaving a function i.e. to printing the trail of Input and output variable. - Memory statistic before entering and leaving the function to have idea about the memory status. What is your expected output? Expected output that all the above should be control with #ifdef , so that these things help in debugging but i don't want that to be part of the final product. What have you tried so far? I am trying to learn ExtUtils::PerlPP but i have not comprehand it properly. I hope, I have explained my situation. Please let me know , if you need more input from me. Regards, Mihir
