I think this might be what you're looking for, unless it was the PB version that Miguel posted.

Have a look at n_osversion by Roland Smith: https://www.topwizprogramming.com/freecode_osversion.html

For example, I'm getting the fileinfo like this:

n_osversion ln_osver
ls_pbvmname = ln_osver.of_PBVMName()
If ln_osver.of_GetFileVersionInfo(ls_pbvmname) Then
	ls_FixedFileVersion = trim(ln_osver.fixedFileVersion)
	if Integer(left(ls_FixedFileVersion, 2)) >= 17 then
		// Appeon 2017 or higher, we use this in u_dw for example.
		ib_Appeon = TRUE
	end if
end if

Hope it helps.
