The GET_ALL function returns SMDEs for all the member names in a PDS, a PDSE, or a concatenation of PDSs and PDSEs. Member-level connections can be established for each member found in a PDSE. A caller uses the CONCAT parameter to indicate which data set in the concatenation is to be processed, or if all of the data sets in the concatenation are to be processed.
If the caller requests that DESERV GET_ALL return all the SMDE directory entries for an entire concatenation, the SMDEs are returned in sequence as sorted by the SMDE_NAME field without returning duplicate names. As with the GET function, all connections can be associated with a single connect identifier established at the time of the call. This connect identifier can then be used to release all the connections in a single invocation of the RELEASE function. Figure 1 shows an overview of control blocks related to the GET_ALL function.
