STEP1

Access method services copies records from a sequential data set, SEQ.DRGV, into a key-sequenced data set, RPR.MYDATA. STEP1's job control language statement:

• INPUT DD identifies the sequential data set, SEQ.DRGV, that contains the source records. The BUFNO parameter specifies the number of buffers assigned to the sequential data set. This improves performance when the data set's records are accessed.

  STEP1's REPRO command copies all records from the source data set, SEQ.DRGV, to the target data set, RPR.MYDATA. Its parameters are:

• INFILE points to the INPUT DD statement, which identifies the source data set.
• OUTDATASET identifies the key-sequenced data set into which the source records are to be copied. The data set is dynamically allocated by access method services.
• ERRORLIMIT identifies the number of errors REPRO will tolerate.
