Can IDE script access Xojo version?

There is a function in Xojo, XojoVersion() that returns a Double that has information about the version of Xojo that is running.

I am a novice when it comes to IDE scripting. Is it possible to access this value in an IDE script?

No, doesn’t look like it: IDE Scripting Commands

When it doubt, though you can always try it in the IDE Script Editor.

I was searching for app version in IDE script and I found this ‘old’ topic.
For Xojo version you can use this constant XojoVersion nowadays.
