NOVAR Prevents the contents of the current window from being cleared, and displays all specified fields that have no visible value. PURGE Specifies unprocessed input received before the form was displayed is to be ignored. Eliminates the possible effects of inadvertent keystrokes or mouse actions. |

Specify a particular instance of a form in brackets beside the object’s name. formfield The name of a particular form field within the currently open form or display. Specify a particular instance of a form field in brackets beside the form field’s name. ([exp1 ],[exp2 ],[exp3 ]) Positive integers or expressions that evaluate to positive integers, that identify a particular form or form field. Exp1 identifies the form number; exp2, the field number; exp3, the instance of the form or form field in the display. At a minimum, either exp1 or exp2 must be specified. |
Comments
The current window must be activated (WINDOW ACTIVATE) for the displayed objects to be visible.
FORM DISPLAY displays form fields with values as they exist at the time the command is executed. If the application program changes the value of a field, the field must be re-displayed if the application user is to see the change.
A masked field that has no data value is displayed without the mask if the field is unavailable to the application user (i.e., protected or guarded). The mask of such a field is shown or suppressed when its availability changes (as a result of the FORM SET command).
Example
form display fGrandTot fInvItem.InvItemTot
Redisplays all fields of one form, and one field of another form.
form display input bell (2,,5)
Sounds the bell while re-displaying all form fields in the fifth instance of form number 2.
Name of the application directory in which the specified object can exist. If the dirname is omitted, the object can be created in any number of directories.
