Chanco requires the name of the user who
wants to send the specified control datagram to the server, usually
specified by the environment variable USER or the
command line option -uuser-id.
Setting CHANGILOGNAME will replace USER, but
may still be overriden by
option -uuser-id.
This environment variable will be set during TCP/IP configuration,
where it is used to specify the REXEC or LPD user.
Chanco uses it to determine the name
of the user who wants to send the specified control datagram to the
server. To use a different name with Chanco, either set
CHANGILOGNAME or add
option -uuser-id
when calling Chanco.
