Description Mike Kaganski 2021-08-02 09:00:50 UTC
Documentation for BASIC "Is" keyword is missing, like in

> If A Is Nothing Then MsgBox "Foo"

E.g.. VBA has [1] for the topic. Generally, "Is" should behave similarly to our "EqualUnoObjects", but not limited to UNO objects. Anyway, even if it's limited to "Is Nothing" in LibreOffice BASIC, it needs a documentation.

[1] https://docs.microsoft.com/en-us/dotnet/visual-basic/language-reference/operators/is-operator
Comment 1 Alain Romedenne 2021-08-05 14:52:39 UTC
Example reference pages for a new help page are:

- https://docs.microsoft.com/en-us/office/vba/language/reference/user-interface-help/is-operator
- https://duckduckgo.com/?t=ffab&q=is+vba+operator&ia=web
- https://www.freebasic.net/wiki/KeyPgOpIs
- https://help.hcltechsw.com/dom_designer/9.0.1/appdev/LSAZ_IS_OPERATOR.html

The help page should consider x-referencing isObject() and EqualUnoObjects() Basic functions in order to clarify their differences.
