Re: RPG compare list code

To follow up on David's comment, you could do something like:

dcl-ds validCodes qualified;
list char(4) inz('ABCD');
array char(1) dim(4) overlay(list);
end-ds;

if %lookup(code: validCodes.array) > 0;
blah, blah...
endif;

You could also load your array from a DB2 table instead if you need something more dynamic.

subject: RPG compare list code


Does anyone know if there is an RPG equivalent to the SQL "IN()" construct? It would be useful to say something like:

If fielda in('A', 'B', 'C', 'D') then...


Instead of this "OR" syntax


If fielda = 'A' or fielda = 'B' or fielda = 'C' or fielda = 'D' then...


I can't find it anywhere if it does exist. I see there is a similar %MAX and %MIN, but nothing like the example above.


Thank you,

Doug
