Show values of an expression in a straight table

[#1]

Hi,

I have a straight table with an expression with a value of either yes or no.

I just want to know, is it possible to show all the Yes values of an expression using a macro??

if possible can someone teach me how to do it..

thanks...

i want to do this automatically using a script....cause I want to generate a dynamic price list where in

if I change a certain price that price and other data associated to it(e.g. ProductID, ProductName) will be saved in a qvd file.
