Hi,

I am trying to test a cobol program in netexpress 5.1 IDE ; when I encounter a cobol READ statement while animating I get the following error.

HEAP[runw.exe]:
Heap block at 00146D38 modified at 00147140 past requested size of 400
HEAP[runw.exe]:
Invalid Address specified to RtlFreeHeap( 00140000, 00146D40 )

The file has the below description

SELECT OPTIONAL DALLOG ASSIGN TO "DALLOG"
ORGANIZATION INDEXED
ACCESS DYNAMIC
FILE STATUS IS DALLOG-STATUS
DALLOG-DVS-STATUS
RECORD KEY IS DALLOG-KEY.

---

FD DALLOG
IS EXTERNAL
RECORD VARYING FROM 5 TO 32763 CHARACTERS
DEPENDING ON DALLOG-RECORD-LENGTH
RECORDING MODE V.
01 DALLOG-RECORD.
05 DALLOG-KEY PIC X(005).
05 FILLER PIC X.
05 DALLOG-CONTENTS PIC X(32757).

What could be wrong ?

Thanks
PTeng
