Dear Arif,

If you will not mistake me, can I ask you something ?

In the last few months there have been numerous queries from you. And so many people responded. Were they useful to you ? What have you done so far ? Have you been able to put together any project ?

This aspect of just remaining at the theory level is fine - but someday, sometime it HAS to translate into HARDWARE. Have you done this ?

You got SDCC. But believe me it is not as easy as using Keil or Ride. And if your DOS proficiency is lacking - God help you. And if you are new to "C" nobody can help you including HIM !!

Raghu

PS: I know this is kind of specific. If you feel offended - I am sorry and there is no need to reply to this.
