Hello,

I need to read input file and replace YyyyyMmm to previous month details i.e. Y2015M09.

Code:

//SORTIN   DD *                       
<SERVER>                                                     
<LOGIN ID & PWD>
PUT  ‘ABCD.A1234.FILE1.YyyyyMmm'      FILE1.TXT                             
PUT  ‘ABCD.A1234.FILE2.YyyyyMmm'      FILE2.TXT
QUIT                                                                           
/*                                     


Output should be
Code:

<SERVER>                                                     
<LOGIN ID & PWD>
PUT  ‘ABCD.A1234.FILE1.Y2015M09'      FILE1.TXT                             
PUT  ‘ABCD.A1234.FILE2.Y2015M09'      FILE2.TXT       
QUIT 
/*   


thank you for your help in advance.

OK, but where are you going to get your date from to work out what the previous month is?

From current date (like DATE2 -1) and pull only yyyy and mm.

And what are you going to do for testing? And what are you going to do for a re-run which is inconveniently "outside" the month which would give the "correct" result?

Bad idea.

If you're doing that, what problem do you have in achieving it? Why would you use FINDREP? The date is in a fixed position and is identifiable.

I tried something below for test runs but it didn't work out.

I was not using FINDREP but IFTHEN & OVERLAY.

Code:

//SORTIN   DD * 
&YYYYMMDD       
/*               



Code:

SORT FIELDS=COPY                                           
INREC IFOUTLEN=80,IFTHEN=(WHEN=INIT,                       
OVERLAY=(81:DATE2-1,C'01',81:81,8,Y4T,LASTDAYM,TOGREG=Y4T, 
           11:87,2,85,2,81,4))                             
IFTHEN=(WHEN=(1,9,CH,EQ,C'&YYYYMMDD'),                     
OVERLAY=(81:DATE2-1,C'01',81:81,8,Y4T,LASTDAYM,TOGREG=Y4T, 
           11:C'Y',12:81,4,16:C'M',17,87,2))
