VPE Rules Table Source Statements

There are three rule statements. Each statement can have one or more parameters.

SYSOPT

Sets global system options.

VSAM

Sets default VSAM processing options.

RULE

Sets processing options for individual files, jobs, and jobsteps.

The SYSOPT and VSAM statements specify the global and default processing options for your system. The RULE statement specifies exceptions to these global and default options. The flexibility to define your own custom global and default processing options and then override them for specific files, jobs, and jobsteps allows you to minimize the number of statements you need to compose in order to implement VPE just the way you want.
