Oops, I thought that I had caught all of these.

Actually I think that he was referring to the compulsory presence of the 
offset, even if it is zero, in the pre-indexed form of addressing.

You are correct though, the immediate value is not needed when using 
offset addressing.  I'll create a patch to fix this and post it later.

Cheers
