Difference between INREC and OUTREC

Postby magesh123 » Mon May 30, 2011 3:49 pm

Hi,
I know the INREC builds the statement before sorting and OUTREC builds the statement.
But both INREC AND OUTREC produces the same result.

Can anyone give the real time example to differentiate the INREC and OUTREC concepts ?

Thank you,
Magesh.

Hello,

Suggest you review some of the topics already posted in the forum that specify INREC and/or OUTREC. If there is something in a topic that is not clear, post what you found and your doubt. SOmeone will be able to clarify.

Also;

It's an excellent tutorial, with lots of examples, that will show you how to use DFSORT, DFSORT's ICETOOL and DFSORT Symbols. You can access it online, along with all of the other DFSORT books, from:

Hope this helps,

Magesh,

The difference in when INREC and OUTREC are processed IS what differentiates them.

For example, if we have these input records:

1111
4444
3333
2222


and we use these DFSORT control statements:

   SORT FIELDS=(1,4,CH,A)
   OUTREC IFTHEN=(WHEN=(1,4,CH,EQ,C'2222'),OVERLAY=(C'5555'))


we will SORT and then do the replace with OUTREC, so the SORTOUT would have:

1111   
5555   
3333   
4444   


But if we use these control statements:

    INREC IFTHEN=(WHEN=(1,4,CH,EQ,C'2222'),OVERLAY=(C'5555'))
    SORT FIELDS=(1,4,CH,A)


we will do the replace with INREC and then SORT, so SORTOUT would have:

1111     
3333     
4444     
5555     


Does that answer your question? If not, you need to explain more clearly what it is you want to know.
