which keil C software to use?

i dunno which keil C evaluation software to download in order to program my microcontroller AT89S51 ?
There is no Keil software that can program your AT89S51.
The Keil software can compile/assemble and link your code, but not program the chip.
to do that you need a $25 "cable" you buy fron Atmel and some free software downloadable from the Atmel website called 'FLIP'

If you are talking of writing or developing program for 89s51 then you can download keil microvision-2 or 3 for that purpose. and if you want to burn the code into the 89s51IC then but some programmer for that or as erik advised

sorry my bad,
yea i meant to write code for buring into the microcontroller.

thanks Erick and Shivaram.

i manage to get it.
just wondering if u guys happen to know any good sites that guide u through C++ codes to send and receive sms from a gsm modem?

this indicates that you are trying to 'run' without even knowing how to crawl.
learn to crawl or you will break a leg walking
WORK through (I did not say 'read') the 'getting started guide' and have a thorough read of "the bible"
THEN, and only then, learn to walk or you will break a leg runng.
do a few simple projects
THEN, and only then, start the project you describe and come back with specific questions

here are the links to "the bible"
