## <Description>
## If <A>flag</A> is true, tracing for all immediate methods is turned on.
## If <A>flag</A> is false it is turned off.
## <Ref Func="TraceImmediateMethods"/> enables tracing for all immediate methods

## <Ref Func="UntraceImmediateMethods"/>, or <Ref Func="TraceImmediateMethods"/>
## with <A>flag</A> equal <K>false</K> turns tracing off.
## (There is no facility to trace <E>specific</E> immediate methods.)
