Hi David,
The reason is that the default scope for a REPLACE command is "NEXT 1" in the currently selected alias. So if your current table is EOF() nothing will happen and no error is generated. This is for very good reason when you think about it :-)
In VFP you can now say REPLACE ..... IN myAlias
