The SIGN clause specifies the position and representation of the operational sign.
- The SIGN clause is allowed only with input, output and update fields whose pictures contain the character "S".
- This clause is allowed only with elementary items.
- It is recommended that the SEPARATE option be used when the SIGN clause is specified in a screen description. If the SEPARATE
option is not specified, a sign denoted by "S" in a PICTURE clause appears as an overpunch.
