Karthik: Recently you have been posting many questions regarding the SDCC compiler. While these questions are not off-topic since SDCC supports the 8051, I would strongly urge you to do the following:

1. Read the manuals and online help available from SDCC. I am sure most--if not all--your questions can be answered by searching for SDCC in google.com and/or visiting the official SDCC website.

2. Post your questions to an SDCC forum or newsgroup. Please understand that most people on 8052.com do NOT use SDCC. I am sure there are places where you can post your questions where other SDCC users may be able to help you.

Regards,
