Help for "Option List" - "ButtonToolTips"

I'm not sure if I already mentioned it, but the help
http://www.opendcl.com/HelpFiles/index.php?lang=ENU&page=Index.htm

tells me:

API Name ButtonToolTipList
Type List of Strings as (Button0ToolTip Button1ToolTip ...)

The same for button-captions:

API Name ButtonCaptionList
Type List of Strings as (Item0 Item1 ...)

But the separator is the pipe symbol |, not a blank. Do I understand it wrong?

The pipe symbol is a convenience to represent a list of strings in the property grid as a single string, but the documentation is correct, the properties are lists of strings.
