AGE(mindays maxdays) is an optional subparameter of SELECT that specifies a list of those entries in the MCDS for only the data sets whose most recent reference is within the specified range of days, or a list of those entries in the BCDS for the data sets that were backed up within the specified range of days.

For mindays, substitute a decimal number from 0 to 999999 for the minimum number of days since you referred to the data sets or since DFSMShsm backed them up.

For maxdays, substitute a decimal number from 0 to 999999 for the maximum number of days since you referred to the data sets or since DFSMShsm backed them up. The maxdays value should be greater than or equal to the mindays value. If the maxdays value is not greater than the mindays value, DFSMShsm lists only the data sets whose most recent reference or backup was exactly mindays days ago.
