When using ANJE, PMDF's BN_MASTER program activates the
username.exe image to change usernames while sending.
username.exe is linked against the system symbol table
SYS.STB, which may not match the version on your system. For this
reason you may wish to relink username.exe prior to using
it.²
If you wish to relink the username.exe image, issue the
OpenVMS command
$ @PMDF_COM:link_username.com
username.exe image is
automatically relinked for you each time you install or upgrade
PMDF.
