Does Xref exist for qb64 ?

[doppler]

The thing I miss most about my assembly writing days is the compiler command to Xref a source file.  On extremely large or multi-module assembly programs knowing all the source lines referencing a variable or value was fantastic.  It was easy to get to all source lines that contained something found in the xref list.  So easy, if a re-write or bug hunt was needed.  It was like shooting fish in a barrel.   Likely the 'C' compiler used in QB64 has that function.  But referencing back to the source would be problematic.

Has someone found or created Xref for QB64 ?
