You can specify a format in the Format Pattern field on the Field Description form. Formats are described in detail in Chapter 13, Formatting Data Values . If you leave the Format Pattern field blank, form gets the format from the default formatting set.
Form selects the appropriate conversion routine based on the data type of the field.
For example, if the data type of the field is boolean , you should enter a format for boolean values in the Format Pattern field. Form applies your format both when displaying a value on the screen, and when accepting input from the operator. On output, form always justifies the formatted value before displaying it. On input, form always removes trailing blanks from the entry, and justifies the entry within the field before formatting the value. When you specify a Format Pattern on an Entry Allowed numeric field, your format pattern should format all values to the exact width of the field.
