What if I need these values to be saved in an array ???
I would expect that your answer is "Then use an Integer Array Parameter", but based on the circumstances I have mentioned before, including those users that aren't versatile in GDL scripting, and maintaining library part's scheme & structure with Graphisoft's GDL styling, it breaks the object's programming scheme, luckily it only affected one portion, but if it was something else it would have caused a big mess
A good friend of mine have once told me that I´m so brute that I´m capable of creating a GDL script capable of creating GDLs.
