Error when trying to write to a variable using inline assemb

I want to write the stack pointer to the variables StkL and StkH. The error I get is that BASCOM is expecting a label instead of a variable. If I use {}, I'll only get one byte of the address, but I want to get both low and high bytes.

Solved it myself. It gave me zeros in the simulator, but on real MCU, the values were correct. The simulator failed to simulate $3D and $3E which are the CPU_SPL and CPU_SPH. Please fix this.

My code was:

why so complex?
Dim StkL As Byte
Dim StkH As Byte
stkl = SPL
stkh = SPH

or :
dim wSTK as Word
wSTk=SP ' sp is defined as word too

About the sim : i will change it. the memory offset of the registers is not available in xmega and thus lower regs are pointing to the wrong memory.
