What syntax to do that with?

lwz %1,0(%U2)
stu %3, 0(%X2)

I'm new to those. (and the above does not compile)

lwz%U2%X2 %1, %2
stw%U2%X2 %3, %2

Why stwu with an offset of zero,

How else to do it? stwu %3, (%2) does not compile for me.

stw %3, 0(%2)

The "u" tells it to write the effective address back to %2 -- but with an offset of zero, the effective address is unchanged.
