11/45 front panel question

ok, two questions. In at least the docs I have (11/45 service manual, user
manual, and handbook), I can't find a clear description of how to toggle a
program into memory.
I'm assuming that when you enter an address in the front panel switches and
hit "load addrs", that the data lights aren't supposed to automatically show
the data value at that location. I'm assuming you must hit "exam" first. Is
this correct? If not, I'd be autoincrementing and seeing the next data
value. Can someone give me a good example of just how to enter two or three
words starting at a given location? I think I can figure this out, but I'd
rather be sure so I don't skip over something that isn't working correctly.
Second, since it's been over 20 years since I did any MACRO-11 programming,
could someone post a simple few line machine code program I can enter and
run to see if the machine will even go into execute mode correctly. Maybe
something that just adds two constants and stores them in another memory
Once I'm sure the machine is working, you can bet I'll dig back into
MACRO-11. For now, I'm just looking for basic store and run sanity check.
Thanks for any advice/help!
