Help putting a byte back together

Okay I'm stuck and need some help. In my program I am polling a port for settings from a dip switch which I'm breaking into 2 numbers. The first 4 and second 4 bits. the code is:

ADDR = PortE ' Read Unit Address
UID = ADDR >> 4 ' Shift Upper 4 Bits of into Lower 4 Bits
LID = ADDR & %00001111 ' Mask-Off (set) Upper 4 Bits to Zero

Now that I've separated the data I need at this point out of ADDR, I want to rebuild it (ADDR) using two different 4 bit numbers. So lets say I now have variables
UID2 and LID2

How do I shift UID2 from the lower to the upper Bits and then combine it with the lower bits of LID2.

For example:
UID2 = 00001011
LID2 = 00001001
I want ADDR to look like 10111001

Thank you,
Hylan

UID2 = UID2 << 4 ' shift nybble back to original location.
LID2= UID2 | LID1 ' bitwise OR the two together.

Semantics, spelling, good beer, not sure.

But maybe that should be, ...

ADDR = (UID2 << 4) | (LID2 & $F)

Actually, a trip to the Sonoma area with little sleep afterward!

Thank you. I'm learning slowly through trial, error, some more error, studying and trying. This forum has been an invaluable source of information.
