assuming that the NO reply holds.
I just looked at Your profile and Your skill set reports IMS/VS APPLICATION PRAGRAMMER
so You should have no involvement in system support
is that true ( the NO Rreply ) for everybody or just for You ?
if the problem is just Yours ... did You contact Your system support for a solution
otherwise pretty unbelievable
that nobody is allowed to logon with a different LOGON procedure
if that is the case Your system people have a very hard task at hand
time to implement the first stage of the disaster recovery plan,
to restore a working copy of the system
or consider the ZZSA standalone editorhttp://www.cbttape.org/~jjaeger
ask somebody to create an iplable tape for it
or try to create Yourself an IPLable CDrom image
and use it to fix the logon procedure
what do the people in the system support group do in their time ?
