Thanks for the workaround.

Hope 3S will provide an official support.

Thank you for your reply.

But that is not my point.

You are correct.

Return value of a method normally also does not work.

However, by typing the method name twice, which is suggested by the code auto complete, it shows no error any more.

I just attached an example.

IF _fb.structMethod().xStructMember THEN

Indeed dosent work;

Zitat:

Using dot operator of a struct property is not supported, which makes the property painful to use.

I see no reason why this is not supported.

The dot operator can be used directly on the return value of a method by typing the method name twice (which is suggested by the auto complete).

Another maybe unrelated point: why the private local data of a function block can be read from outside?
Shouldn't the compiler prevent it?

Following is an example to make my point clear:
