The start-up screen has a standard structure showing all the fields of the file with the field name on the left.

If you wish to do some data-mining or selection on certain fields then simply click on those field names. When you click on the field it will become red, clicking again on that label will de-select that field and return the colour to black.

When you have selected the required fields, eg Age, Sex and Zip-Code click on the “Show all Records” button.
