Sort sum with a zoned field

Postby xcspg3 » Fri Jun 02, 2017 11:36 pm

Hi,
I can't understand how the sum of positive fields gives an unsigned result. Only the sum of negative fields is signed field.

The sysin is
Select all
//SYSIN    DD *                  
 SORT FIELDS=(1,125,CH,A)        
 SUM FIELDS=(126,15,ZD)  


The sum of this 3 records is positive and the field is unsigned
Select all

Try adding a

review your understanding of negative/positive zoned representation
also remember , the concept of signed/unsigned applies usually ONLY to the binary integer representation
in 32 bits You can represent a 2**31 SIGNED number or a 2**32 UNSIGNED numnber

When I tell somebody to RTFM or STFW I usually have the page open in another tab/window of my browser,
so that I am sure that the information requested can be reached with a very small effort

thanks for this info. But how to fix the same issue with OUTREC instead of sum fields ?

OUTREC FIELDS=(1:1,643,644:361,15,ZD,ADD,391,15,ZD,M11,LENGTH=15) ->>> the value created at 644 having F0 instead of C0

I resolved the issue usingTO=ZDC:
Select all
OUTREC FIELDS=(1:1,643,644:361,15,ZD,ADD,391,15,ZD,TO=ZDC,LENGTH=15)

vinayjai - please do not tailgate other peoples topics. In future, start you own topic.
The problem I have is that people can explain things quickly but I can only comprehend slowly.
Regards
Nic
