Launching 6 .vbs scripts simultaneously from a single script
I think I addressed that eventuality, at least in an implied manner,
when I offered that there were TWO reasons that his script wasn't
working the way he wanted it to work. One was that the Run wasn't being
setup correctly or that the first script was NOT pausing, but rather it
was using all available CPU cycles. WSH scripts tend to do that, which
I assume is why the Sleep method was added in version 2.
Therefore, it would seem to me that additional efficiency is possible
ONLY if the former case (bWaitForReturn = True, instead of False) is
true. If any script is using (very nearly) all of the CPU cycles, the
addition of (supposed) parallel processes will have negligible (or even
negative) impact on the efficiency of the overall process. If there had
been a pause in 'GUNAs' script AND the bWaitForReturn was False or not
defined, then he wouldn't be reporting the scripts wouldn't run
concurrently, would he?
