I do not need to be protected against myself

#define U16   unsigned short
#define U8DX  unsigned char   xdata * data

UCDX  GCDX232ptr;    // receive rs 232 pointer
U16 GStemp;
.....
  GStemp = (U16) GCDX232ptr;
  GStemp &= 0xFF00 ;
  GCDX232ptr = GStemp ;

works, why does

  (U16) GCDX232ptr &= 0xFF00 ;

not work

There should be a way. I am short of memory and need get rid of GStemp

There's an intermediate possibility that should avoid warnings, given the original examples:

GCDX232ptr = (U16)GCDX232ptr & 0xFF00;

This eliminates the need for GStemp, even if it doesn't use &=.

thanks Drew

GCDX232ptr = (U16)GCDX232ptr & 0xFF00;
dos work, in my frustration, the closes I got was
(U16) GCDX232ptr = (U16)GCDX232ptr & 0xFF00;
which does not.

Thanks again

Erik
