Can we use DFSORT to search the dataset with a key word, and then replace it by the other word we specify?

i.e.

Input File A:
AAABBBCCDDDEEE
CCCAAABB
CEDCCC

run after the DFSORT coding

Ouput File B:
AAABBB11DDDEEE
111AAABB
1ED111

All 'CCC' change to '111'.

Thanks...
David

You say
Quote:
All 'CCC' change to '111'.
but in your example of input and output you show EVERY 'C' replaced by '1'.

This DFSORT job will give you the output you show by replacing every 'C' with '1'. I've assumed your input file has RECFM=FB and LRECL=80, but you can change the job appropriately for other attributes.

Code:

//S1    EXEC  PGM=ICEMAN
//SYSOUT    DD  SYSOUT=*
//SORTIN DD DSN=...  input file (FB/80)
//SORTOUT DD DSN=...  output file (FB/80)
//SYSIN    DD    *
  OPTION COPY
* Set up ALTSEQ table for TRAN=ALTSEQ.
* X'C3' = 'C'.  X'F1' = '1'.
  ALTSEQ CODE=(C3F1)
* Use TRAN=ALTSEQ to change 'C' (X'C3') to '1' (X'F1').
  OUTREC FIELDS=(1,80,TRAN=ALTSEQ)

Dear Frank,

I would like to ask one more stupid question. I never use the program highlight below. Is it still the DFSORT?

S1 EXEC PGM=ICEMAN

PGM=ICEMAN and PGM=SORT are ways to invoke the primary sort product at your site. If you have DFSORT as the primary sort product at your site, PGM=ICEMAN and PGM=SORT will invoke DFSORT.

Frank, Thanks for your reply. I've tried your method. It do work. If I want to make a little change as follows. Can the DFSORT also solve it?

Change all 'C' to 'cat' and all 'B' to 'boys'. It means the length may extend.

i.e.
Input:
CAAAC
AACBBC

Output:
catAAAcat
AAcatboysboyscat

Regards,
David

DFSORT doesn't have any built-in functions for doing that kind of find and replace.

<It does as of July, 2008 - see my post later on>

hello,

Actually I am looking for a replacement for '$' with space (1 Byte only). How do I do that ???

Actually I was referring to the ASCII table for hex equivalent but it was of not help ...

Any kind of help would be really appreciated.

Hi,
Try this.

Code:

//S1    EXEC  PGM=ICEMAN                               
//SYSOUT    DD  SYSOUT=*                               
//SORTIN    DD *                                       
AAA$BBCCDDDEEE                                         
CCC$AABB                                               
CED$CC                                                 
//SORTOUT   DD SYSOUT=*                               
//SYSIN     DD  *                                     
  OPTION COPY                                         
* SET UP ALTSEQ TABLE FOR TRAN=ALTSEQ.                 
* X'5B' = '$'.  X'40' = blank.                           
  ALTSEQ CODE=(5B40)                                   
* USE TRAN=ALTSEQ TO CHANGE '$' (X'5B') TO ' ' (X'40').
  OUTREC FIELDS=(1,80,TRAN=ALTSEQ)                     


your o/p will look like

Code:

AAA BBCCDDDEEE 
CCC AABB       
CED CC         


Thank you
Krishy

Hi Krishy,

It is working now.

Thanks a ton but tell me one thing .... what table are you are referring to figure out '$' as 5B ...

As I mentioned in my previous message that I referred the ASCII table but couldn't find what you got and what you got is working fine ... so plz do tell me what table you are referring to ???

Thanks once again.

The ASCII and EBCDIC character sets are different. You need to look at the EBCDIC values for ALTSEQ. Here's a link to a table that shows the ASCII characters on the left and the EBCDIC characters on the right:

www.ncsa.uiuc.edu/UserInfo/Resources/Hardware/IBMp690/IBM/usr/share/man/info/en_US/xlf/html/lr425.HTM

If you go down the page on the right side, you'll see that blank is X'40' in EBCDIC and '$' is X'5B' in EBCDIC. So the ALTSEQ statement you need to change every '$' to a blank is:

Code:

      ALTSEQ CODE=(5B40)

Hi,
The simple thing that I do generally is,open any member in EDIT mode and type the letter which you want to convert.

Then use the HEX on function and see it's hex value and use that one in
ALTSEQ CODE.

When you type $0 and use the HEX on ,you can see the values like this.
54
b0

Thank you
Krishy

What if I want to replace two chars at a time

For example if I want to replace '$' with '0' (zero) and ' '(space) with '0'.

so the input file

abc$a888 9999

would look like:

abc0a88809999

How can we do this in just one step.

Rgds,
Mohit

If by low values you mean X'00', and by high values you mean X'FF', you can use the DFSORT technique shown previously with:

Code:

   ALTSEQ CODE=(0040,FF40)


If you mean something else by low and high values, you need to be more specific about what exactly you mean.

Hi Frank,

By low values and high values, I do not mean 00 and FF. One of my friends said to find out low values, the command " F P'.' " can be used and this command shows low values in the form of dots, but the hex value of these dots vary(to name some 12, 2D, 05 etc).


Similarly is there any command to find out the high values and also how to replace such characters using space.

Thanks

Vinoth

I think what you are describing is the picture-string FIND command for 'invalid' characters
and that what you want to do is change those characters with spaces.

In ISPF edit you would do it such;

C p'.' ' ' all

are you looking for a batch method to do this?

Hi all,

Yes, I want to replace the invalid characters with blank space, any batch method to do that would be really helpful.

Thanks,

You can now use DFSORT's new FINDREP function available with z/OS DFSORT V1R5 PTF UK90013 (July, 2008) to do this kind of thing quite easily like this:

Code:

//S1   EXEC  PGM=ICEMAN
//SYSOUT    DD  SYSOUT=*
//SORTIN DD DSN=...  input file
//SORTOUT DD DSN=...  output file
//SYSIN    DD    *
  OPTION COPY
  INREC FINDREP=(INOUT=(C'C',C'cat',C'B',C'boys'))
/*


For complete details on the new FINDREP function and the other new functions available with PTF UK90013, see:
