RE: SQL UDF RETURNS DECIMAL(13,2) LANGUAGE RPGLE

For the sake of the archives, I found this. I needed parameter style
GENERAL.

Anybody remember a CNLRQS (Cancel Request) key? Was that just on the
selectric-typewriter-style console of the 360/370?

Well, it must be UDF problem week where I am. I posted to the RPG list
since there is an RPG/SQL partnership involved.



System is at V5R3M0



I have created a new SQL function with a partner RPGLE *SRVPGM (because
really there are bunches of functions). A sample CREATE FUNCTION looks
like
this:

CREATE FUNCTION MYLIB/perAccum(CHAR(9),DECIMAL(4,0)

, DECIMAL(2,0),DECIMAL(11,2)

, VARCHAR(1), VARCHAR(32))

RETURNS DECIMAL(13,2)

RETURNS NULL ON NULL INPUT

LANGUAGE RPGLE

EXTERNAL NAME 'MYLIB/DTACVTFN(accumValue)'

NOT DETERMINISTIC

NO SQL

NO EXTERNAL ACTION

PARAMETER STYLE SQL

ALLOW PARALLEL

NOT FENCED



The prototype that goes with this one looks like this:

D accumValue PR 13P 2 ExtProc('accumValue')

D employee 9 Const

D year 4P 0 Const

D month 2P 0 Const

D amount 11P 2 Const

D accumType 1 Const Varying

D accumName 32 Const Varying



The issue that I have is that any use of this function is returning
Decimal
Data error (MCH1202), and I have not been able to figure out why. The
values are in fact returned, and they are in fact valid from RPG's
perspective (I've proven with code like the following)

/If DEFINED(DEBUGGING)

msg = 'accumValue() returning ' + %char(rtnvalue)

+ ' for accumulator ' + %Char(I)

+ ' of ' + %Char(nbrAccums) ;

sndPgmMsg('CPI8859': msg) ;

/EndIF

Return rtnValue ;



I also tried changing from "13P 2" to "13S 2", but that didn't change
the
symptom. Can any of you tell me what I've done wrong here, or tell me
what
else you need to see in order to be able to assist? I'm missing it!
(BTW:
I have also verified that the incoming data is all valid decimal data;
it's
the return that's failing.)


Thanks!
