Before you close the cursor, try
EXEC SQL GET DIAGNOSTICS :rowsFetched = ROW_COUNT;

A very change thing going on with the SQL in my program:

Loop control for going through selected rows is as follows here:

//
exsr PosFile ;
//
DOU RowsFetched = 0 or SqlCode <> 0 ;
exsr FetchNext ;
For rx = 1 to RowsFetched ;
Eval-Corr CS = MT(rx) ;
//
// .. Lots of code to process each row…
//
ENDFOR;
EndDo;

exsr CloseCK ;


Subroutine Posfile declares and opens cursor CK...


//
svkey = sv15x3ad + %char(sv15pudt) +
%editc(sv15ot:'X') + %editc(sv15pro:'X') ;
EXEC SQL Declare CK Cursor for
select
CS154X4USR ,
….. <...list of columns...>
CSDLTUSR
from cs15p001
where CSACTINA <> 'I'
and ( : fleread in ('00', '01') or
: fleread = '02' and current_user = CS15NADUSR or
: fleread = '03' and current_user = CS154X4USR )
and (CS15OT <> 0 and CS15PRO <> 0)
and (:SVKEY < CS15X3AD || char(CS15PUDT) ||
digits(CS15OT) || digits(CS15PRO))
order by CS15X3AD, CS15PUDT, CS15OT, CS15PRO ;
//
exec sql Open CK ;
//
endsr ;


Then there is subroutine FetchNext:
exec sql Fetch Next from CK for :Rows_To_Fetch rows
into :MT ;
rowsFetched = SqlErrd(3) ;
*in99 = (rowsfetched = 0) ;

What's going on is in the generated code from the SQL precompiler at the
FETCH statement, pasted following from debug in the 5250 session running
the program, copied below. At that first line (with the arrow indicating
which one), before it executes, ROWS_TO_FETCH is equal to 1000 (one
thousand). After it executes, SQLER5 is still equal to ZERO, even though
ROWS_TO_FETCH is still 1000. 😮😮 Can somebody tell me how to fix this?

//* exec sql Fetch Next from CK for :Rows_To_Fetch rows
//* into :MT ;
SQLER5 = ROWS_TO_FETCH; <==========
SQLER6 = -4;
SQCALL000013(
SQLCA
: SQL_00043
: MT
);
