F7 on Log(strinfo) does not register

Sub t1
Dim strinfo As String
strinfo = _
"OS.AvailableExternalMemorySize = " & OS.AvailableExternalMemorySize & CRLF
File.WriteString(File.DirDefaultExternal, "info.dat", strinfo)
Log(strinfo)
End Sub

' *** F7 on strinfo in Log() does not work because Log is not a function ?
Thanks, Jerry

This is related to a bug in v1.80. The find references tool fails to find local (only local) variables in the last line of the sub. It is fixed for the next update.
