Ya.... From what (little) I know about 3270 (and 5250 for AS/400s?)
reminds me of HTML forms with the mainframe as the web server and the
terminal as the client web browser. What with the mainframe sending
[protected,hidden] fields to the terminal that displayed them and
trusted what the terminal sent back. *headshake* Times were different.
I am guessing that there is also security through obscurity based on
what information was available at the time.
You could go to a VM monitor and type IPL AIX and
watch UNIX boot up.
I wonder if USS / OMVS terminal ~ application on more modern mainframes
still run into issues.
