Valid Formats for DAYS

Valid formats for the DAYS parameter, and how they relate to DCAL, are described below.

In the following non-periodic scheduling formats:

• n is an integer from 1 to 31.
• Multiple values can be specified (separated by commas) in any order.
• DCAL should not contain the name of a periodic calendar.

  Table 140 Non-Periodic Scheduling Formats

  Format	Description
  ALL	All days in the month. If ALL is specified, other DAYS values cannot be specified with it. If a DCAL calendar is not defined, schedule the rule on all days in the month. If a DCAL calendar is defined, schedule the rule only on the working days indicated in the calendar.
  n,...	Specific days of the month. If a DCAL calendar is not defined, schedule the rule on the specified days. If a DCAL calendar is defined, schedule the rule only when a day is defined as a working day in both the DAYS and the DCAL parameters.
  +n,...	Days of the month in addition to the working days specified in the DCAL calendar. DCAL is mandatory.
  –n,...	Order the rule on all days except the nth day from the beginning of the month. DCAL is mandatory.
  >n,..	Schedule the rule on the indicated day if it is a working day in the DCAL calendar; otherwise, schedule the rule on the next working day of the month that is not negated by a –n value in this parameter. This format is frequently used for holiday handling. DCAL is mandatory.
  <n,...	Schedule the rule on the indicated day if it is a working day in the DCAL calendar; otherwise, schedule the rule on the last previous working day of the month that is not negated by a –n value in this parameter. This format is frequently used for holiday handling. DCAL is mandatory.
  Dn,...	Schedule the rule on the nth working day from the beginning of the month. DCAL is mandatory.
  –Dn,...	Schedule the rule on all working days except the nth working day from the beginning of the month. DCAL is mandatory.
  Ln,...	Schedule the rule on the nth day (or nth working day if DCAL is defined) counting backward from the end of the month. DCAL is optional.
  –Ln,...	If DCAL is defined, schedule the rule on all working days except the nth working day counting backward from the end of the month. If DCAL is not defined, schedule the rule on all days except the nth day counting backward from the end of the month. DCAL is optional.

In the following periodic scheduling formats:

• n is any integer from 1 through 63 and i is any valid period identifier (or * for all periods).
• An * can be specified as the n value in format DnPi to represent all days. (* is not a valid n value in formats –DnPi, LnPi, and –LnPi.)
• A period can span any number of days, but by default, no more than 33 days can elapse after the appearance of one identifier in a period until the appearance of the next matching identifier in the same period. Once a gap of 33 days has been reached, the period automatically closes. (The 33-day default can be changed by the INCONTROL administrator.)

The name of a periodic calendar must be specified in DCAL. For details concerning periodic calendars, see IOA Calendar Facility.
