Accessing Wn+offset from asm

[peterverkaik]

Hi,

I am trying to use instructions
mov [Wns+offset],Wd
mov[.B] Wns,[Wnd+offset]

but the compiler generates error on these instructions.

asm
vpTimer_S0:
mov _vpBase, W2
mov [W2 + nmTimer1], W1 ;'load value with highbyte clear
inc W1 ;'increment lowbyte
mov.b W1,[W2 + nmTimer1] ;'keep highbyte clear
end asm

Why is the instruction not supported?

regards peter
