Re: Calling an ServiceProgram with a returnvalue

I am a seasoned c# developer, you're right i just used this pseudo code to make my point clear.
You would'nt want to make a call to an external system to get something as simple as the day of week.
My silly reply: DayOfWeek is an Enum, so if you want it as a number, you do:

int dayOfWeekAsANumber = (int)myDate.DayOfWeek;

A completley silly reply ( since it doesn't answer the how to
question ) and no doubt your example is a puesdo example.

But you can derive the week day number in .Net using something like
the thisdate.dayofweek method

Sorry I'm on a mobile so I'm not sure of the exact syntax!

As I said not a lot of use :-) but an interesting question you have
posed anyhow

Hi all,

To call an iseries program or serviceprogram from .net, i wrap the
call inside a storedprocedure, and then use that storedprocedure
from my .net application.
Works like a charm, except, i can't figure out how to call a
serviceprogram that has a return value.
something like this:
d DayOfWeek PR 1 0
d InputDate D DatFmt(*iso)
For any given date, it returns the day of week as a number;

I thought about wrapping it in a function, but i couldn't make that
work.
I could of course, wrap such a function inside another
storedprocedure, and add the returnvalue as an extra parameter, but
i was wandering if somebody knew
howto do this.

I find it a bit strange that it is possible to call a subprocedure
inside a serviceprogram directly, but that you cannot get at the
returnvalue.
Perhaps there is some way to define this in the storedprocedure, but
there is so little documentation about this.

I'm on a V5R3 machine, and i use IBM.Data.DB2.iSeries assembly.

thanks for all replies.
