Question: Text output via label: How combine variable and text?

Hello,

I would like to combine and output different text modules that are saved in variables as strings but cannot get rid off the brackets and quotation marks

use DocumentTools in
textOne:="Hello";
textTwo:="How are you?";
SetProperty(Label0, caption,[textOne, textTwo]);
end use;

I alway get  ["Hello", "How are you?"] istead of Hello How are you?

If i remove the brackets [ ] after caption, the output is fine but only the first element appears. Hello

If I try the printf command, which apparently should remove the marks, the label won't output anything at all.

use DocumentTools in
textOne:="Hello";
textTwo:="How are you?";
SetProperty(Label0, caption,[printf(textOne), printf(textTwo)]);

end use;

How ist it done? Help would be much appreciated.

Thanks a lot!

Regards, Ben
