The SP, SS and S edit descriptors control the output of the optional plus (+) sign within numeric output fields. These descriptors have no effect during execution of input statements.
These specifiers correspond to the SIGN= specifier values PLUS, SUPPRESS, and PROCESSOR_DEFINED, respectively.
Within a format specification, a sign editing descriptor affects all subsequent I, F, E, EN, ES, D, and G descriptors until another sign editing descriptor occurs.
