Parameter relationships

Selection parameters are cumulative; each selection parameter within a statement is modified by subsequent selection parameters. Selection parameters on a single line are related by an AND condition, whereas selection parameters on separate lines are related to preceding lines by an OR condition.

The following example indicates that the volume ID must be TEST01 and the data set name must be APPROD.VNDR.MASTER.

The following example indicates that the BMC AMI Storage function is applied if either the volume ID is TEST01 or the data set name is APPROD.VNDR.MASTER.

Multiple values for a single selection parameter are related by an OR condition; that is, when several values are specified for a single selection parameter by enclosing the list of values in parentheses, any of the specified values will satisfy the selection. The following examples demonstrate this relationship:

The following example indicates that the second name qualifier must be DBYTD or DBQTR or DBDLY:

When you specify multiple selection parameters with value lists, the selection is satisfied by a combination of OR and AND conditions, as the following example shows:

The example indicates that the BMC AMI Storage function is applied if the second name qualifier is either DBYTD or DBQTR and if the third name qualifier is either RECEIPT or ORDER.

Selection parameter specifications are usually contained within a single line; however, they can be continued onto multiple lines. Continuation is indicated by a non-blank character in column 72. Therefore, parameter specifications continued on the next line are treated as being connected by AND logic. For example, the following statement indicates that the data set name must be APPROD.VNDR.MASTER and the volume ID must be WORK for the BMC AMI Storage function to be applied. If the second line was not a continuation line, the two parameters would be related by OR logic.
