Re: Object copy function question

[Linus <olivier.cruilles@xxxxxxxx>]

Thank you all for your answer, that confirm there is no magic function already present in Gambas to copy custom Class objects array.

It’s fine, I made mine for the specific Class object array I manipulate into my project.

I just wanted to be sure about the way to do because It took me few hours to find my bug related to the copy of Class object array.
