The "!"

[TheVig]

Ok...I understand in QM the "!" is used as not equal...ie

Code:

Copy      Help

str Test
Test="On"
if(Test!"Off")
,out "On"
,
;outputs "On"

But I see it all over the place in QM and don't quite get the syntax all the time. Could I get some examples of different ways the "!" is used and explanations of what is going on in each case.

Thanks,
