I am using Keils uvision2 V2.38 (full)
I am writing a small C function which is suppose to replace the assembly function

My rest code is written in assembly and the assembler (asm51) is used

The data declaration is done as

t33 EQU 53H
t34 EQU 54H
t35 EQU 55H
t36 EQU 56H
t46 EQU 0A7H

Now here the t32 is a macro definition
(if I am not wrong as I have never used assembly but do have knowledge of it since it was there in the curriculum)

and it is referred as variable in the assembly program as

MOV A,t32
CJNE A, #1FH,Chk


and I want to access the same t32 from my C function

I tried defining the variables as

t32 DATA 52H
t33 DATA 53H
t34 DATA 54H
t46 DATA 0A7H


But it does not give me the access in C if I wrote

extern unsigned char t32;


The addressing of the variables at that particular location cannot be changed as some places the address is used as

MOV R0,#t46


I have only two days to complete the program
and I have finished my C function and it is working fine but
I am not able to patch it at old assembly function


Please help
