I want to pull the bits off of a register a nibble at a time. Is SLDL
on an even/odd register the best way to go?
If so, I'm having a bit of trouble moving the bits to the top end. For
example, I want this:
009A - 9A00
I thought I could do it this way:
LA R3,X'9A'
SLAR3,24
Lindy,
Try SLL instead of SLA...

If so, I'm having a bit of trouble moving the bits to the top

try to use sll instead of sla.

Lindy:
You mention moving a nibble but your INTENDED code doesn't do that. You are
just moving the 9A from the LO byte to the HO byte. A nibble as I recall is 4
bits of a byte, either the LO or HO 4. To move out a nibble:
LA R4,X'9A'
SRDL R4,4
SRLR5,28
That will yield:
R4=
Try SLL.

Seems like you're trying to move a byte to the high order. Instead of
shifting why not just ICM?

Thanks to all! Especially pointing out different ways to do it, like this.
The first assembler language I learned to any proficiency was for a PIC
microcontroller. (RISC and Harvard) It had I believe only 33 instructions which
were easy to learn. On the other hand, you really had to think to
