I tried it with an alias in the query and got the same result. I think Naomi got by using macro substitution in place of the eval.


>The 'current.sc1_2000' in the second case references original table/cursor alias not the one used in the query. See http://www.berezniker.com/content/pages/visual-foxpro/queries-and-functions-which-accept-alias-parameter
