Need help with user command

[Paul]

Maybe this explanation will help someone who is looking at USER
the way I was.

USER track=/usr/bin/gotrack001
track=@rn    'sends script @rn via STDIN
tracknum=track  'returns tracknum via STDOUT

gotrack001 script has:
read tracknum

as one of the first lines.

No one ever explained user to me this way in 30 years or 20 since user
was included.
