Determining "Business Days" (i.e. No Saturday/Sunday)

[Jon.Paris@xxxxxxxxxx]

I have a DayOfWeek procedure that I use as part of my class.  You can use
it to avoid weekends, but of course it doesn't understand Christmas,
Thanksgiving etc.  Code is below.

     H NoMain DatFmt(*USA)

     D/Copy QRPGSRC,DateProto3  <<<  Proto should look like the PI below

      ******** Start of procedure definitions

      * DayOfWeek - Calculates day of week (Monday = 1, Tuesday = 2, etc.)
for
      *             any date.
      *           - Input:  WorkDate (Date field in *USA format)
      *           - Return: Single digit numeric

     P DayOfWeek       B                   Export

     D                 PI             1S 0
     D WorkDate                        D   DatFmt(*USA) Const

      *     AnySunday can be set to the date of ANY valid Sunday

     D AnySunday       S               D   INZ(D'04/02/1995')
     D WorkNum         S              7  0
     D WorkDay         S              1S 0

     C     WorkDate      SubDur    AnySunday     WorkNum:*D
     C     WorkNum       Div       7             WorkNum
     C                   MvR                     WorkDay

     C                   If        WorkDay < 1
     C                   Return    WorkDay + 7
     C                   Else
     C                   Return    WorkDay
     C                   EndIf

     P DayOfWeek       E
