 The newest five cycles must be stored in the outside storage location SAVE,

and all others in their HOME location.

Figure 9-26 Single VRS example

Figure 9-27 shows the data sets and the location retained by the single VRS

definition.

9.10.3 VRS chain with one NEXTVRS operand

In the second example (Figure 9-28), we are using the NEXTVRS operand to

have an additional LOCATION definition. The request for this VRS is almost the

same as the one in Figure 9-26; the difference is that the newest five cycles must

always be in the HOME location.

The tasks for this VRS specification are as follows:

 Retain ten cycles of each matching data set group.

 All instances of a data set created on a single calendar day are considered to

be a single cycle.

 The newest cycle (0) must be stored in the HOME location. You do not need

to specify the LOCATION(HOME) operand, because HOME is the default.

 The next five cycles (-1 to -5) must be stored in the outside storage location

SAVE.

– All other cycles (-6 to -9) should be retained in the HOME location.

definition.

VRS chain with two NEXTVRS definitions

The third example (see Figure 9-30) shows a VRS with two NEXTVRS definitions

to have more than one outside LOCATION definition. The only difference

between the first and the second example is that the data sets must be moved to

a secondary storage location.
