General Information for DAYS

Negative values take precedence over positive values when determining whether a job must be scheduled on a certain date. If a negative value (that is, format –n, –Dn, –Ln, –DnPi, or – LnPi) in either the DAYS or WDAYS field prevents a job from being scheduled on a date, the job is not scheduled on that date even if a positive value (such as Ln) in a basic scheduling parameter would otherwise result in the job being scheduled on that date.   

A maximum of eight periodic values of type DnPi, –DnPi, LnPi, and/or –LnPi can be designated in any desired order.

If periodic and non-periodic values are mixed when specifying the DAYS parameter, processing depends on the calendar type specified in the DCAL parameter:

• If a non-periodic calendar is specified in the DCAL parameter, only non-periodic values in the DAYS parameter are processed; periodic values are ignored. In this case, negative periodic values (that is, –DnPi, –LnPi) are also ignored and do not supersede other values.
• If a periodic calendar is specified in the DCAL parameter, all periodic values and the negative non-periodic value -n in the DAYS parameter are processed; all other non-periodic values are ignored.

The MONTHS parameter is ignored when periodic values are specified in the DAYS parameter.

For information about certain exceptional situations in the interaction of the DAYS and MONTHS parameters, see MONTHS: Basic Scheduling Parameter .

The DAYS parameter cannot be used with the PDS, MINIMUM, and DATES parameters.
