Table 1 describes, in decision table format, DFSMSdss restore actions for physical processing of SMS-managed data sets. The specified RESTORE command keywords and the existence of the data set are shown in the upper half. The actions taken are shown in the lower half.

Figure 1 describes general DFSMSdss actions for both physical and logical restore on non-VSAM data sets. It is not a program flowchart. Use it to clarify the restore actions on non-VSAM data sets under varying conditions.
