SELECT and EXCLUDE Rule #8

If both SELECT and EXCLUDE commands are specified for a given action command, the following rules apply:

• If an EXCLUDE command tests true, the data set is bypassed whether a SELECT statement tests true or not.
• If no EXCLUDE tests are met, at least one SELECT command must still test true for the data set to be processed.

For example,

SCAN REALVOLS

EXCLUDE VOLUMES=PROD/
EXCLUDE VOLUMES=SYS/
SELECT CRITERIA=(DSORG,EQ,VSAM),DSN=/

REPORT CLDATA

would report on VSAM clusters on other than your PROD or SYS volumes. It would not report on non-VSAM data sets, nor would it report on any VSAM clusters on your PROD or SYS volumes.
