Harbour/xharbour Diff : 7/57 - PASSING OBJECT VARIABLES BY REFERENCEby Przemyslaw Czerpak

Both compilers support passing object variables by reference though this functionality in xHarbour 

is limited to pure instance or class variables only and does not work for SETGET methods. 

In Harbour it works correctly.

This code illustrates the problem:

      proc main()
         local oBrw := tbrowseNew()
         ? oBrw:autoLite
         oBrw:autoLite := !oBrw:autoLite
         ?? "=>", oBrw:autoLite
         p( @oBrw:autoLite )
         ?? "=>", oBrw:autoLite

      proc p( x )
         x := !x

Harbour prints:
      .T.=> .F.=> .T.
but xHarbour prints:
      .T.=> .F.=> .F.
without generating any compile or run time errors.
