The enable field statement allows a previously disabled field to receive user input. The enabled field is redrawn using the settings specified in the Properties window for the field.
enable field field_name{, field_name, field_name, ...}
• field_name – The name of the field to be enabled. Multiple fields can be enabled by listing each field’s name, separated by a comma. Because the fields can be in different windows, be sure to fully qualify the field names not in the current window.
Fields with the Editable property set to false in the Properties window can’t be enabled using the enable field statement.
