|data|| (optional) specifies the new flag value, which can be one
of the following (SQL*Forms compatible) flags:
|name|| specifies particular fields by name.
|number|| specifies particular fields field sequence number.
|attribute|| specifies a bitmask.
|flag = true||specifies that all fields with the specified attribute are executed; If flag is not specified, all fields that do not have any of the field attributes are executed. These last three flags are not reset by the system; the application must reset these flags. Review trim.h for more details.|
