Hi Stephane.

>Is it possible, like with the "ON ERROR" command, to redefine or re-direct the Error Event of a form?

No, but you can control what happens in the Error method.

Here's how you could do that in the Error method (this is just off the top of my head, so don't expect to copy and paste it and have it work <g>):

use MYTABLE
if not used('MYTABLE')
* error must have occurred, so do something here
endif

procedure Error && the Error method of the form
lparameters tnError, tcMethod, tnLine
do case
    case tnError = &&something that indicates a problem with the table
        return
* rest of cases go here
endcase
