You can't do this right now but you could set an arbitrary high limit and then use the result of a count over sys columns for the table with %SubArry to restrict the number you access.

In this case though you appear to be building the null map for a known file - so why not just use Extname with the *null option and have the compiler generate the list you want?

ie, i would like the gF1Null dcl-s stmt to be :

dcl-s gF1Null int(5) dim(%columns('ORDD30WF1')) ;

instead of hardcoding the column count.

ORDD30WF1 is an externally ddl described work file.


(make sense?)

dcl-ds gF1Ds extname('ORDD30WF1') inz qualified end-ds;
dcl-s gF1Null int(5) dim( 8) ;
dcl-ds gF2Ds extname('ORDD30WF2') inz qualified end-ds;
dcl-s gF2Null int(5) dim(20) ;

select t1.*,t2.*
from ordd30wf1 t1 left outer join ordd30wf2 t2
on t1.ordnbr=t2.ordnbr and t1.ordlinnbr=t2.ordlinnbr

exec sql fetch mycsrF1 into :gF1Ds :gF1Null, :gF2Ds :gF2Null ;

if gF2Null(1) = -1 ;
status( %char(gF1Ds.ordnbr) ) ;
else ;
status( %char(gF1Ds.ordnbr) + ' ' + gF2Ds.FDNAME ) ;
endif ;
