No; Actually the problem is one of not laying proper foundations before starting to build your house!

You need to take some time to study the basics of the 8051 architecture, and the Keil tools that you wish to use.

Standard advice for beginners:

First, you need to read the uVision Getting Started guide, and work through the example projects in it.
This will give you a proper introduction to the tools - rather than just jumping in at the deep end without actually uderstanding what they do or how to use them.

You need to read the following documents - commonly referred to as "the bible" for the 8051:

Are you also a newbie to 'C' programming in general?
If so, you'll also need a good 'C' textbook.

You will need to read the Data Sheet for your particular processor, and the Manual(s) for any development boards, etc.
