Here is an example that will at least print the answer. Doing comparisons with 
the result would be more complex.


TYPE registers=cc,a,b,dp:BYTE; x,y,u:INTEGER
DIM regs:registers
DIM hx,lx,hu,lu:BYTE
regs.x=$FE47
regs.u=$CF39
hx=LAND(regs.x,65280)/256
lx=LAND(regs.x,255)
hu=LAND(regs.u,65280)/256
lu=LAND(regs.u,255)
PRINT"$";
PRINT USING "h2",hx;lx;hu;lu

RUN
$FE47CF39

Cumbersome but the value printed is correct.
