Making sections absolute when they don't really need to be is a bad idea.
Only one module in the whole project can use UDATA h'100'.  If another
module tries to do this too, the two sections will collide and you will get
the "can not fit section" linker error.  You would also be hard coding where
the banked memory in bank 0 starts, which varies between parts.  Yucc.

Why not just do it right?  If you want to force particular banks at assembly
time, create named sections in the linker for each bank.  Then reference
these named sections in the source code:

bank1  udata

Any number of modules can do this, and there won't be a error unless the
total memory requested for bank 1 exceeds the size of bank 1.

See my linker files where I set up named sections for exactly this purpose.

What's a "freg"?
