Section 10,26: S

 (Normal Signing)

 Restores the option of producing plus characters (+) in numeric
 output fields.  The S descriptor counters the action of either the
 SP or SS descriptor by restoring to the processor the discretion of
 producing plus characters on an optional basis.

 This descriptor affects fields all that follow it, until an SP or
 SS is encountered.  The S descriptor affects all subsequent I, F,
 E, D, and G editing (in the same FORMAT statement) during the
 execution of an output statement.
