Re: RNF0571 The second parameter of LOOKUP is not valid

Nooooooooo….


That will make it a table and the behaviour is different. Tables are a
_very_ ancient feature of RPG that pre-date even RPG III - we should have
dropped them in RPG IV and didn’t for some reason. Consider them deprecated.

%Lookup works just fine on any array - including those defined via group
fields. Also works on DS arrays in V7 and later.

Try renaming your data structure to begin with "TAB". My recollection is

that the %lookup op-code does not work on tables named something else in
the same way the column LOOKUP worked.

Subject: RNF0571 The second parameter of LOOKUP is not valid

Hello all,

I have what I think is a simple question........I have an array with an
associated data structure defined like this:

HCAArray ds 363 dim(100) qualified
HCAID 3 0
HCAHarms 360


Basically this is to be an array with two fields, an ID (HCAID) and a

large

text field (HCAHarms). I'm then trying to do a lookup on the large text
field portion of this array as follows:

eval IndexF = %lookup(workharms:HCAArray.HCAHarms)

However I'm getting the RNF0571 compile error. Second parm of LOOKUP is
not valid. I know the second parm has to be an array, but I guess I

thought

it was. I've also tried this variation:

eval IndexF = %lookup(workharms:HCAArray)

And I get the same error. I basically want to search the HCAHarms field
for a value that I have in a work field (workharms). Any thoughts out
there on what I'm doing wrong? All help appreciated. Thanks!

Bill
