Ho Jon

No the array has not been loaded ….

Ok for “If %Elem( xMagArt ) > 0;”

But:

why without *auto it works ??

the behavior with *auto id different ??

when we use *auto we must always check “If %Elem( <array>) > 0 ??

what do you mean whe you say “ although I'd prefer RPG to simply report 0.”
??



Thanks in advance

If not then the element count is zero and you'd get an error I suppose -

although I'd prefer RPG to simply report 0.

To avoid it condition the %Lookup with:

If $Elem( xMagArt ) > 0;

Maybe your idx3 is wrong. Use %ELEM()

I think would be strange that idx3 was wrong, as his value is 1 and why
without *auto it works ??

Anyway i will try

Thanks

Hi all

I’m try to use the *auto keyword in a Ds Array ; i have defined this Ds



Dcl-Ds xMagArt Qualified Dim(*auto:256) inz ;

Key;

xMag like(zMag) Overlay(Key);

xArt like(zArt) Overlay(Key:*NEXT);

End-Ds;



when i try to run :



Idx2 = %Lookup(Mag+Art:xMagArt(*).Key:1:Idx3);

Keep in mind (Idx3 = 1 )



i receive RNQ0121 An array index is out of range

Where am i wrong ??

If i not use *auto, it works



Thanks in advance
