Possible to convert .a51 files to .c files?

"is it possible for me to convert these files into c code"

"Convert" is not really the word here.
You will need to read the assembler files, understand what they're doing, and then re-implement that in 'C'.

But why do you want to do it anyway? There is no problem in having a mixed Project containing both 'C' and assembler.

"I'm very new to this software"

What do you mean by that?
Do you mean you alrady have experience with other tools, but not Keil?
Or do you mean you are a complete novice to microcontroller programming?

Hi Neil,

thanks for ya reply.
I'm new to micro-controller programming, thanks for informing me abt the combined use of C and assembly language.
