Spencer:

Use an immediate IIF when you want to make an assignment depending on a condition. An immediate IIF should not be used when you want to run a method if and only if an expression is True.


For example:

myVar = IIF(SomeCondition, SomeValue, SomeOtherValue)

performs faster than

IF SomeCondition THEN
   myVar = SomeValue
ELSE
   myVar = SomeOtherValue
ENDIF

but

=IIF(SomeCondition, DoSomething, .F.)

is just plain silly and it is better to use

IF SomeCondition THEN
   DoSomething
ENDIF

instead.
