OKL - On Key Label
PEM - Properties, Events and Methods

For a grid, what I do is put code to change the sort order in the Click method of the grid headers.

>sorry I am not familiar with those 2 anacronisms. So what event do you apply when the user clicks on the grid heading. Actually, I don' think you can specify the heading but rather the whole grid. (haven't used grids too much)

>>>I see the standard way to sort a list in standard apps is to click on the column's title bar. Is that done with a grid in vfp. Can it be enabled with the browse window?
>>>-Thanks.

>>Grids are the VFP way [and IMO better way] of providing browse functionality to your users. I do not know of a way to do what you want using a regular browse window except by using OKLs. A browse window has no PEMs.
