>i fetch in data,method,layout and other,i didn't see PEM.

PEM is short for Properties, Events and Methods. You see them in the Properties window which you can poen several ways. Right-click on the grid, then select properties. Or in the Foxpro toolbar there is a button for it. Generally it opens by itself when you open a form for editing.


>what is the relasion ship between command window and grid.

None. The command window is a special form for you to control VFP, typing commands for immediate action. A grid is a control you drop in forms.
