I admit to being an Oz newbie, but - thankfully - I know [or at least I
*think* I know] the difference between the two ;) !
I actually posted the complete code, including the AVGDEV declaration, so it
should be in the mailing list archive in its entirety. However, here is some
of the missing code:
...
!AVGDEV = @AVGDEV
end
end
...
N AVGDEV
in
{ComputeStatistics}
{Application.exit 0}
end
Thanks again.
