MEMORY window prob

Sachin Shintre

Hi every one
I am trying to debug an assembly program
using keils Uvision2 C51 compiler,
When I try to see the change in perticular vriables value in watch window but if that variable is added in a address window by its address then I cannt see any thing.

In 89C52 the 256 bytes of RAM are devided in two parts one direct addressable & other indirectly addressable i.e.

t43       DATA     96H
MOV R0,#t43
MOV @R0,#20h

this will write 20h in t43 & can be seen in watch window but if I use memory window and say
D:0x96 then the change cannt be seen

please help
sachin
