Before Copy
Figure 4-5 IEBCOPY copy operation
Copy control command example
In Figure 4-5, two input partitioned data sets (DATA.SET5 and DATA.SET6) are copied to an
existing output partitioned data set (DATA.SET1). In addition, all members on DATA.SET6 are
copied; members on the output data set that have the same names as the copied members
are replaced. After DATA.SET6 is processed, the output data set (DATA.SET1) is compressed
in place. Figure 4-5 shows the input and output data sets before and after copy processing.
The compress process is shown in Figure 4-7 on page 116. Figure 4-6 shows the job that is
used to copy and compress partitioned data sets.
