Yes I have checked the new features of AC22, but the thing is i am still asking for GDL method, because i want to create a more complex calculations with GDL from the exam i gave. For example i will put some conditions, and if it is satisfied i will do some calculations, if not gonna do some another calculations etc.
i think i can deal up with the mathematical and conditional part, but first i need to read and list areas of one type zone(they also in an seperate layer, maybe i can use for filtering?)
Just checking to make sure that you are aware that no GDL object can know anything about any other object ... except in the case of labels, which know about the one object that they are associated with. So, if you want info about a type of zone in a GDL solution, you would need to create a Zone Label that calculates what you want - for that one zone. While it could write a single number to a text file, I don't think that's what you want.
You can create a schedule of those zones that has all of the calculated values for all zones ... and then can Publish that to a text file. You cannot actually "print" other than to a log file.
GDL is a language just for creating objects, not for automating anything about ARCHICAD itself. The C/C++ API (see the Developer Forum here) is what lets you program solutions that go beyond that.
