During a D/R exercise using GDPS, we were shutting down the
exercise. We had consoles for both the production and exerciseing up
for monitor. When someone too lately shouted "Not that system C".

Well, I remember a senior colleague's lucky escape ...
Quite early in my sysprog career, before PR/SM came along and gave us
our own test LPARs, a lot of our testing was done on the programmers'
test system on one specific 2h lunchtime slot per week.
Despite that system being thought of a development one only, it wasn't
unheard of for some production batch work to run there, and in any case
it shared its JES2 spool with the production system. Back in those days
we didn't run a sysout archiving tool.
My colleague was demonstrating how we could test JES2 function using a
secondary JES2 (ie one started as an ordinary STC, as far as I remember,
under the primary JES2). Commands to the secondary one just had to be
prefixed by a different subsystem commmand character from any used for
primary subsystems.
At the end of our tests my colleague, while continuing to explain the
purpose of successive commands didn't pay enough attention to what they
were typing as they entered the command to purge everything from the
spool and was about to hit enter when I - very much the junior - said:
STOP! and asked: shouldn't that have the secondary JES's command
character?
Swearing ensued, but not as much as would have done if the command had
been issued.
