Valid Formats for WDAYS

Valid formats for parameter WDAYS, and how they relate to WCAL, are described below.

In the following non-periodic scheduling formats:

• n is an integer from 1 through 6 or 0 (zero), where 1 = the first day of the week (Sunday or Monday, depending on the standard at your site) and 0 = the last day of the week (that is, Saturday or Sunday).
• Multiple values can be expressed (separated by commas) in any order.
• WCAL must not contain the name of a periodic calendar.

  Table 275 Non-Periodic Scheduling Formats

  Format	Description
  ALL	All days of the week. If ALL is specified, other WDAYS values cannot be specified with it. If a WCAL calendar is not defined, schedule the mission on all days in the week. If a WCAL calendar is defined, schedule the mission only on the working days indicated in the calendar.
  n,...	Specific days of the week. If a WCAL calendar is not defined, schedule the mission on the specified days. If a WCAL calendar is defined, schedule the mission only when a day is defined as a working day in both parameter WDAYS and the WCAL calendar.
  +n,...	Days of the week in addition to the working days specified in the WCAL calendar. WCAL is mandatory.
  –n,...	Schedule the mission on all days except the nth day from the beginning of the week. WCAL is mandatory.
  >n,...	Schedule the mission on the indicated day if it is a working day in the WCAL calendar; otherwise, schedule the mission on the next working day (within the next seven days) that is not negated by a –n value in the parameter. If none of those seven days is a working day, the mission is not scheduled. This format is frequently used for holiday handling. WCAL is mandatory.
  <n,...	Schedule the mission on the indicated day if it is a working day in the WCAL calendar; otherwise, schedule the mission on the last previous working day (within the preceding seven days) that is not negated by a –n value in the parameter. If none of those seven days is a working day, the mission is not scheduled. This format is frequently used for holiday handling. WCAL is mandatory.
  Dn,...	Schedule the mission on the nth working day from the beginning of the week. WCAL is mandatory. Use D0 or -D0 to refer to the 7th working day from the beginning of the week.
  –Dn,...	Schedule the mission on all working days except the nth working day from the beginning of the week. WCAL is mandatory.
  Ln,...	Schedule the mission on the nth working day counting backward from the end of the week. WCAL is mandatory.
  –Ln,...	Schedule the mission on all working days except the nth working day counting backward from the end of the week. WCAL is mandatory.
  DnWm,...	(Where m = 1 through 6). If WCAL is defined, schedule the mission on the nth working day of the mth week of the month. If WCAL is not defined, schedule the mission on the mth appearance of the nth day of the week during the month. WCAL is optional. A maximum of 11 DnWm values can be specified.
  	Note: When specifying DnWm with a calendar in the WCAL field, do not code n as 0. This may produce unpredictable results.

In the following periodic scheduling formats:

• n is an integer from 1 through 6 or 0, and i is any valid period identifier (or * for all periods).
• WDAYS periodic identifiers are counted on a week by week basis. Calculations do not cross week boundaries (unlike DAYS periodic identifiers that can cross month boundaries).
• The name of a periodic calendar must be specified in WCAL. Refer to IOA Calendar Facility for details concerning periodic calendars.

  Table 276 Periodic Scheduling Formats

  Format	Description
  DnPi,...	Schedule the mission on the nth day of period i in each week, from the beginning of the week.
  –DnPi,...	Schedule the mission on all days except the nth day of period i in each week, from the beginning of the week.
  LnPi,...	Schedule the mission on the nth day of period i in each week, counting backward from the last day of the week.
  –LnPi,...	Schedule the mission on all days of period i except the nth day of period i in each week, counting backward from the last day of the week.
