I was taught that to make it easy to read, do the following:
BL *+4+2
LR R1,R2
or
BL *+4+2+4
LR R1,R2
LA R3,0(,r1)
It may not look right in your email, but the branched around
instructions are indented one extra character.

I don't remember who taught me the technique, though it must have been at UofW in the
early 80s. I internalized it as "This isn't a 'real' branch-that is, we aren't going
very far, just skipping a single instruction". And I would never, ever, ever
consider doing it for more than one instruction.
