Help with compiling in codewright

Hi All

I'm trying to integrate uVision so that it compiles code written in codewright. I have set up the following command line in codewright to use the compiler

c:\keil\c166\bin\c166.exe %r%e

it returns messages saying invalid base address and unidentified identifier in the following file REGST10F269.

I'm fairly new to this and would appreciate any help.

Thanks in advance
Matthew
