Re: You should have been sacked
"Also, isn't AS/400 able to provide some pretty fine grained permissions? Fine grained enough that a trainee left alone on the weekend couldn't enter such a "global" command that reset everything rather than just the one connection he intended?"
At that time, the authorizations structure of the AS/400 wasn't that fine grained yet. Besides that, it was most likely the same command and he just forgot to replace the default "*ALL" in one parameter, something no authorization structure can fix. Been there and done that as an AS/400 programmer since 1993.
