Hi,

I am trying to write a sort for comparing two files of record length 17200.

F1 - LREC 17200
F2 - LREC 17200.

The requirement is to extract records that are updated or added.

Code:

JOINKEYS FILE=F1,FIELDS=(20,25,A)           
JOINKEYS FILE=F2,FIELDS=(20,25,A)           
JOIN UNPAIRED,F1,F2                         
REFORMAT FIELDS=(F1:1,17200,F2:1,17200,?)   
OPTION COPY                                 

OUTFIL INCLUDE((34401,1,CH,EQ,C'B',AND,           
               (1,250,BI,NE,17201,250,BI,OR,     
               251,250,BI,NE,17451,250,BI,OR,     
               501,250,BI,NE,17701,250,BI,OR,     
               751,250,BI,NE,17951,250,BI,OR,     
               1001,250,BI,NE,18201,250,BI,OR,   
               1251,250,BI,NE,18451,250,BI,OR,   
               1501,250,BI,NE,18701,250,BI,OR,   
               1751,250,BI,NE,18951,250,BI,OR,   
               2001,250,BI,NE,19201,250,BI,OR,   
               2251,250,BI,NE,19451,250,BI,OR,   
               2501,250,BI,NE,19701,250,BI,OR,   
..
...
...
..
               15501,250,BI,NE,32701,250,BI,OR, 
               15751,250,BI,NE,32951,250,BI,OR, 
               16001,250,BI,NE,33201,250,BI,OR, 
               16251,250,BI,NE,33451,250,BI,OR, 
               16501,250,BI,NE,33701,250,BI,OR, 
               16751,250,BI,NE,33951,250,BI,OR, 
               17001,200,BI,NE,34201,200,BI)),   
               OR,34401,1,CH,EQ,C'2'),BUILD=(17201,17200)


It appears we cannot handle condition beyond 32752 bytes.

Please advise.

Thanks
Magesh

Magesh_J,

The maximum limit for LRECL is 1 to 32,760 for non-VSAM data sets. You are creating 17200+17200 = 34,400 which exceeds that limit.

Ideally I would write a simple COBOL program for matching and finding out the differences.

Or just use the Compare program built into ISPF. That can be run in batch mode.

While Sort can do this, if the task is compares, it's probably easier to start with a utility designed for that task.
