Yes, it should be possible. Take a look at the FPCUnit (unit testing framework) included with FPC. The testing framework invokes methods and passes parameters around.

As long as you know the signature of the method you can cast the pointer to the method to an approbiate method variable and call that. For dynamic calls you'll need to wait for Invoke() support which is on the ToDo list, but there's no ETA yet.

Does the framework knows the method signature at compile time?
I will take a look. Thanks for the tip.

Will this result in a new kind of Pascal Script support ? (In the German Forum there recently had been discussions on Pascal script not working decently on 64 Bit archs.)

Don't know as I'm not using PascalScript, but potentially it could be.
