A code assist function which suggests candidates responsive to a parsing of a partial program instruction statement by determining a current cursor position in the partial program instruction statement; parsing the partial program instruction statement before the current cursor position; generating a list of candidates to be inserted at the current cursor position responsive to the parsing of the partial program instruction statement; applying a user-selected preference to the list of candidates to generate a suggested list of candidates; displaying the list of suggested candidates; allowing a user to select one of the list of suggested candidates; and inserting at the current cursor position the user-selected suggested candidate. User-selectable preferences may be selected such as a longer or shorter list of candidates; a longer or shorter representation keyword candidates; a full syntax or partial syntax representation of a candidate; and a character case representation of a candidate.
