Bob
MUCH appreciated.
After your last e-mail I revisited the web page and read and re-read the
article. If this was a Monday morning AND I had'nt had my usual 20 cups of
coffee, I could excuse myself for being so thick, however, this is NOT Monday
morning AND i've had 30 cups of coffee, ergo, I must be thick. This last e-mail
is much better.
Again thanks

Alan,
I covered that in a presentation I did at COMMON a few years ago.
Here's the source code:
P WeekDay B EXPORT
D WeekDay PI 32A
D InputDate D CONST DATFMT(*ISO)
D DS
D Days 70A INZ('Sunday +
D Monday +
D Tuesday +
D Wednesday +
D Thursday +
D Friday +
D Saturday')
D Day 10A Dim(7) Overlay(Days)
C TEST(E) InputDate
C If %ERROR
C Return 'Invalid Date'
C Endif
** Note: Date validation is done here to avoid -1 return value
C return Day(DayOfWeek(InputDate))
P WeekDay E
This is calling a slightly different GetDayOfWeek procedure. I called in
DayOfWeek so it'll have a different name from the one in the article.
The main difference is that this DAYOFWEEK procedure accepts a valid
date data-type as its input parameter whereas the article was concerned
with that strange CL date CYMD format.
Below is the modified DayOfWeek procedure.
P DayOfWeek B EXPORT
** Procedure interface for DayOfWeek function
D DayOfWeek PI 10I 0
D InputDate D CONST DATFMT(*ISO)
** Base date is based on calendar changed date
D BaseDate S D INZ(D'1582-10-14')
D nDayOfWeek S 10I 0
D nDays S 10I 0
C TEST(E) InputDate
C If %ERROR
C Return -1
C Endif
C InputDate SubDur BaseDate nDays:*DAYS
C CALLB 'CEEDYWK'
C Parm nDays
C Parm nDayofWeek
C return nDayOfWeek
P DayofWeek E

Subject: Dear all,
Dear all,
I came across an article by Robert Cozzi, Jr at
http://www.mcpressonline.com/mc/.5bfbb72f
titled "Moving to ILE CL" (and before anyone starts saying that I'm in
the wrong forum, this is an RPG question) I decided it was high time
for me to start delving into creating procedures, and binding and such.
Plus the end result of this article would give me the day of the week
for a particular date, which is something that I need for a project I'm
working on. So - killing 2 birds with one stone. Anyway, in the
article/procedures/programs, what is returned is a numeric value
representing the day of the week. What I want ot return is the actual
English representation. Monday, Tuesday etc. I attempted to implement
arrays, but ended up with not being able to create a module due to
compile errors. My question to the forum, how can arrays be implemented
in rpg procedures, if possible. I have included the RPG module that I
ended up with, and it should be apparent what array I am attempting to
implement. Much appreciated and thanks in advance.
