Re: Keyed Array Data Structure %LOOKUPLT

You can't do what you are trying to do with %LookUpXX

For DS arrays, only %LOOKUP is allowed. The variants (LT, etc.) are not supported in part because there is no way to designate the sequence of the keyed field.

You can sort based on any subfield, but not search. Given that you have such a small array perhaps a simple search loop will do the job for you.

Hi,

I have this lookup problem. Can't believe it.
IBM reference says : A "Keyed Array Data Structure" is an array data
structure with one subfield
identified as the search or sort key.

I don't see how to identify one subfield as the search or sort key or where
this is explained.

This compiles :
$I = %LOOKUP ( myDate : myArray(*).DATE )

This doesn't
$I = %LOOKUPLT ( myDate : myArray(*).DATE )

My Array DS :

D myArray DS DIM(10) QUALIFIED
D CODE LIKE(refcode)
D DATE LIKE(refdate)

Thanks
