Process specific control

GDDM V3R2 Base Application Programming Reference

GDDM uses the Process Specific Control (PSC) order to store picture prolog and symbol-set information in a GDF object. Because it does not add any graphics data to the picture, the order is ignored by the GSPUT call. For information on the different PSC orders, see topics 10.9 to 10.10.25.
