Hi,

I have an existing sort card like below :

Code:
OPTION COPY                                                         
INREC OVERLAY=(371:174,4,ZD,ADD,+1,EDIT=(TTTT),375:170,2,377:172,2)
OUTFIL OMIT=(371,8,CH,LT,DATE1,           
    AND,160,02,CH,NE,C'00',                               
    AND,160,02,CH,NE,C'11',                               
    AND,160,02,CH,NE,C'14',                               
    AND,160,02,CH,NE,C'15',                               
    AND,160,02,CH,NE,C'16'),                               
  BUILD=(1,370) 



I need to add following condition to the above sort card:

INREC IFTHEN=(WHEN=(60,9,CH,EQ,C'000000000'),OVERLAY=(60:C' ')) .

I tried by giving this new condition aftre INREC OVERLAY and removing my INREC keyword (as I think only one INREC can be given at a time ).it is not giving error but also not formatting the records as I want .

Do i need to use some keyword like HIT NEXT ? for continuation.

Kindly suggest.

Thanks,
Aishvarya

Please use the "code" tags for your sort cards, it preserves the spacing.

I don't know that we can answer your question without having an idea of what you want to do.

So,

Some sample input, sample output (both nicely "Code"d, recfms/lrecls and a description of what you are trying to achieve.

Use below...
Code:

//SYSIN    DD *                                                         
 OPTION COPY                                           
 INREC IFTHEN=(WHEN=INIT,                                               
       OVERLAY=(371:174,4,ZD,ADD,+1,EDIT=(TTTT),375:170,2,377:172,2)), 
       IFTHEN=(WHEN=(60,9,CH,EQ,C'000000000'),                         
       OVERLAY=(60:C'         '))                                               
  OUTFIL OMIT=(371,8,CH,LT,DATE1,                                       
  AND,160,02,CH,NE,C'00',                                               
  AND,160,02,CH,NE,C'11',                                               
  AND,160,02,CH,NE,C'14',                                               
  AND,160,02,CH,NE,C'15',                                               
  AND,160,02,CH,NE,C'16'),                                             
  BUILD=(1,370)                                                         
/*                                                                     


Also you could have omitted records which are not having 00\11\14\15\16 at 160,2 before INREC is applied itself using OMIT COND

We have some records with zeroes in columns 60-68 and I want to convert them into spaces by adding the condition in existing sort card.

Be aware that you have only put one space to be overlayed.

Sambhaji,

Is there any advantage in using the OMIT condition first than using that in OUTFIL ?
I suppose since the number of records that would be processed is reduced it might increase the performance.
Am I right? icon_question.gif

Do you realize that you are creating an invalid date in pos 371 if the date happens to Feb 29th of a leap year when you just add 1 to the year portion without validating the month and date?

For example if you are running on 2013-FEB-28 and if your input has the following date

2012-02-29 now adding 1 to the year makes the date as 2013-02-29 and your omit condition would fail. I am showing the filtering and INREC manipulation as I am not really sure what the date check is. If you explain your date check condition, I will suggest an alternate solution. I think your date check is similar to another topic here where I provided a solution.

ibmmainframes.com/viewtopic.php?t=55811

I would suggest filtering the data before instead of doing it on OUTFIL and use positive conditions instead of negative conditions.

Code:

//SYSIN  DD *
  INCLUDE COND=(160,2,SS,EQ,C'00,11,14,15,16')
  INREC IFTHEN=(WHEN=(60,9,ZD,EQ,0),OVERLAY=(60:9C' '))
//*
