Beginning of the next month is not calculated correctly.
You need to add 1 moth to the current date, then determine then day of month
and subtract it from the result and add 1 day.
... but why to calculate the beginning of the next month with RPG and not
SQL
Exec SQL Set :Beginning_Of_Next_Month = Last_Day(:MyDate) + 1 Day;
Or in a sigle Step:
Exec SQL Set :HoldDayOfWeek_ISO = Week_ISO(Last_Day(:MyDate) + 1 Day)

Subject: problem with DAYOFWEEK_ISO in an SQLRPGLE program
Hi everyone
We are on V7r3
I am trying to determine the first business day of the following month I
have a simple program to start of with It takes a date, calculates the first
of the following month, and then finds the day of the week (ISO) The code is
below (like I said - its simple) Using debug, I can see that
HldDayOfWeek_ISO from DayOfWeek_ISO(Beginning_of_Next_Month) is zero (which
is NOT a correct value) But HldDayOfWeek_ISO2 from
DAYOFWEEK_ISO(CURRENT_DATE) is 3 - which is correct - today being Wednesday
***NOTE*** - The value of Beginning_Of_Next_month is '2019-02-01' ,
according to debug Can anyone see what is wrong with this code?
Why I am not getting the DAYOFWEEK_ISO for Beginning_Of_Next_Month?
As always, all answers replies gratefully accepted
dcl-s MyDate date
inz(d'2019-01-02');
dcl-s Beginning_of_Next_Month date;
dcl-s HldDayOfWeek_ISO zoned(2:0);
dcl-s HldDayOfWeek_ISO2 zoned(2:0);

exec Sql Set Option Commit=*NC, CLOSQLCSR=*ENDMOD, DECMPT=*PERIOD;
exec Sql Set Option DATFMT = *ISO, NAMING = *SQL;
Beginning_of_Next_Month = MyDate - %Days(%subdt( myDate:*days)-1) +
%months(1) ;
exec sql
select DayOfWeek_ISO(Beginning_of_Next_Month)
into :HldDayOfWeek_ISO
FROM SYSIBM.SYSDUMMY1;
exec sql
SELECT DAYOFWEEK_ISO(CURRENT_DATE)
INTO :HldDayOfWeek_ISO2 FROM SYSIBM.SYSDUMMY1;
*inlr = '1';
return;
