Hi

There is no return code 160 in Vsam upto my knowledge. Its there in DB2 return code. Just check out it may be mainframe response code also.

You are trying to open an EMPTY VSAM file and getting return code - 160

REPRO INFILE(INPUT) OUTFILE(OUTPUT)
IDC3300I ERROR OPENING USERID.TEST.ESDS
IDC3351I ** VSAM OPEN RETURN CODE IS 160
IDC0005I NUMBER OF RECORDS PROCESSED WAS 0
IDC3003I FUNCTION TERMINATED. CONDITION CODE IS 12

IDC0002I IDCAMS PROCESSING COMPLETE. MAXIMUM CONDITION CODE WAS 12
