Hi,

In my program i have a variable of word size (unsigned short)
and two pointers which point to the two bytes of this word.

word TMP;
byte *ptr_TMP_l, *ptr_TMP_h;

In my code i try to assign it in the following way.
It needs a cast to increase the adress by 1 byte instead of a word.

ptr_TMP_l = & (byte) reg_TMP;
ptr_TMP_h = & (byte) reg_TMP + 1;

When compiling my source from RHIDE (default options) i get the
message: invalid lvalue in unary `&'

I've tried more () what ya call them? but it keeps complaining.


Any help will be greatly apreciated.

Donnie Roos.
