Antonio,
I was using the harbour64 that comes with FWH64 package (Oct 2011)
However after changing to new harbour64_vc64_20120127 I am getting the same message:
Error 0021 Incorrect number of arguments in AT Passed: 3, expected: 2
Please see below the AT() function source code , (maybe this can help to fix the problem), found on harbour:
