How about writing to a global:

That won't work (because of the lock). What I'd like to do is, in
some sense, the opposite of what you usually want to do with
concurrent processes. You generally, define critical sections in
your code (using locks or a similar construct) to prevent
interference from other concurrent processes, but I want to make
the interference visible, and the more dramatically the better.
I think Kevin is the only one to offer a solution. I hadn't thought
of it when I replied here, but his solution can be made to work using
$INCREMENT
S ^GLOBAL=0
J1 ;
F I=1:1:100 S ^GLOBAL($INCREMENT(^GLOBAL))="A"
Q
J2 ;
F I=1:1:100 S ^GLOBAL($INCREMENT(^GLOBAL))="B"
Q
I still can't think of any way to do it in Standard MUMPS.
