The default display format for INT64 data type is "->,>>>,>>9" (the same as the default display format for INTEGER.) You can define an INT64 field or variable to be viewed as (VIEW-AS) a fill-in field, text widget, combo-box, radio-set, or slider.

Note that if you specify VIEW-AS SLIDER for an INT64 field or variable, the value must still remain within the -2147483648 to +2147483647 integer range.
