FWIW you can have many more than 4. Even before we had the extra "-r" commands, 
I'd been sending delimited type data over that channel and parsing the @PM field 
to pass multiple fields of data.

... -r "1234AACA1234GGGG3456"

a=mid(@pm,"1","4");b=mid(@pm,"5","4";c=mid(@pm,"9","4");d=mid(@pm,"13","8")

In fact I always wondered what the deal was in adding only three more. I never 
did see the limitation that was solved by creating @px, y and z????
