Yuriy Samartsev

I'm using the Keil C51 Tools and have successfully written 8051 programs only in assembly language. Now I need add C code to my assembly program.
After the i add C code to my assembly code Keil C51 has grasped a part of space DATA memory. Now i can not use DATA space for some assembly variables. My C code running in the start programm and i can sharing DATA space _DATA_GROUP_ with my assebly variables. How can i make DATA segments for sharing DATA space between _DATA_GROUP_ and my assembly variables?
