Steps to Reproduce Behavior

  3. Click OK. You can add a few records if you wish.
  4. Type MODIFY STRUCTURE in the Command window.
  5. In the Fields tab of the Table Designer select the first field char1, and click Delete. (You must click the Delete button in the dialog box rather than the press the Delete key on the keyboard.)
