I have already translate the program to keil's.It does not work
I can imagine it did'nt. You probably used the eval version that locates everything in different places in order to protect it from being used as a production software. That will never produce a match.
If you have the budget, go for a full Keil or Raisonance, those are 'native' '51 compilers as opposed to IAR which is an 'adapted' '51 compiler.

Switching compilers often is a harrowing experience, but if you switch to a better one it is worth it.
