Where is USER set?

[Ralph Finch]

I am trying to run only part of my .login, depending on whether I am
logging in or sourcing it from a script file (run all of .login when
logging in, part when running in batch from a script file).  On one
machine, a Sun 4/330, this works ok, that is: on login, USER is set
and is me; and when run from a batch system, USER is not set.  However
from a Sun 4/260 it doesn't work when run from batch:  USER is set,
and it's somebody else!  What would cause this?
