Direct access data sets GDDM V3R2 Base Application Programming Guide SC33-0867-01 |
|
Direct access data sets are used by GDDM for the Master Print Queue data set, used by GDDM to control requests for queued printer output made by calls to DSOPEN, FSOPEN, DSCLS, and FSCLS. GDDM ensures the integrity of the Master Print Queue, because it is written to by multiple TSO users and by the GDDM TSO Print Utility. GDDM ensures that at any one time, no more than one instance of GDDM has the Master Print Queue available for input/output processing. |
