Hi, I have a requirement like below
I have a file with address information and I would like to filter (include) only records which has address information. Address position is 1 to 40.
When I tried the below sort card, it didn't work out. Could you help me with any other way
//SYSIN DD *
SORT FIELDS=COPY
INCLUDE COND=(1,40,CH,NE,X'00',AND,1,40,CH,NE,X'40')

| You want to exclude all records with spaces or binary-zeros in the first 40 bytes? |

Hello,
Can there be both x'00' and x'40' in the same 1st 40 bytes?
Or does the first 40 bytes need to be completely space or x'00' to be skipped? |

Other than the INCLUDE being more difficult tp read due tpo the negated condition, it should be working.
Which means what you have described is not the full story.
Please post the sysout from a step which did not work, show some sample input records and expected output and provide the RECFM/LRECL of the input, and output if different.
Pay close attention to Dick's question.
Consider re-writing the INCLUDE as OMIT:
| Code: |
OMIT COND=(1,40,CH,EQ,X'00',
OR,1,40,CH,EQ,C' ') |
NB. TS had X'40', which in the test for a field longer than one byte compared the value "padded" with binary zeros, due to the use of a hexadecimal constant. Using C' ' for a space, a character constant, causes the comparison to be padded with space and works correctly. |

Hi Bill,
I tried the following :-
| Code: |
//STEP0001 EXEC PGM=SORT
//SYSOUT DD SYSOUT=*
//SORTIN DD *
A
//SORTOUT DD SYSOUT=*
//SYSIN DD *
SORT FIELDS=COPY
OMIT COND=(1,20,CH,EQ,X'00',
OR,1,20,CH,EQ,X'40')
//STEP0002 EXEC PGM=SORT
//SYSOUT DD SYSOUT=*
//SORTIN DD *
A
//SORTOUT DD SYSOUT=*
//SYSIN DD *
SORT FIELDS=COPY
OMIT COND=(1,20,CH,EQ,X'0000000000000000000000000000000000000000',
OR,1,20,CH,EQ,X'4040404040404040404040404040404040404040')

STEP0001 produced output of 2 lines
STEP0002 produced 1 line of output
I was expecting the result to be the same for both steps ie. only 1 records out
Am I missing something ?

I think I must be :-)
Why are you expecting only one record output, when the first record of your input is neither 20 binary-zeros nor 20 spaces? |

Hi Bill,
does this
| Code: |
SORT FIELDS=COPY
OMIT COND=(1,20,CH,EQ,X'00',
OR,1,20,CH,EQ,X'40')
|
equal this
| Code: |
SORT FIELDS=COPY
OMIT COND=(1,20,CH,EQ,X'0000000000000000000000000000000000000000',
OR,1,20,CH,EQ,X'4040404040404040404040404040404040404040')

A guarded Yes. When I tried it, mine got rid of a line of 40 binary-zeros or 40 spaces, but retained lines containing at least one other character.
However, TS's code is equivalent, and doesn't work (in some unknown way).
I'm using DFSORT. |

I got confused by the above statement, Gerry's input has spaces at pos 1-20 in record-1 right?  |

Looks like when ever we need to provide X we need give the value equal to length in Include or OMIT
Coudlnt find any details of that in Manuals
Pretty strange for me
Edit: Also the same does not happen when using C' ' |

Hi,
I'm also using DFSORT.
Also my first record is all blanks.

Bill, just so I'm not confused, which of my 2 options did you use ?
Pandora-box, so you are getting the same results as I'm getting

I had a look at the DFSORT manual and it is pretty much clear about field-to-constant comparison rules when the operands differ in length.
| Quote: |
Character and hexadecimal strings are truncated and padded on the right.
The padding characters are:
X'40' For a character string
X'00' For a hexadecimal string. |
In Gerry's card, the comparison was with hexadecimal strings and as per the rule, both were padded with X'00' on the right before comparison.
So the equivalent of
| Code: |
SORT FIELDS=COPY
OMIT COND=(1,20,CH,EQ,X'0000000000000000000000000000000000000000',
OR,1,20,CH,EQ,X'4040404040404040404040404040404040404040') |
will be
| Code: |
SORT FIELDS=COPY
OMIT COND=(1,20,CH,EQ,X'00',
OR,1,20,CH,EQ,C' ') |
Hope this makes sense now. |

That'll be it Arun.
I just can't bring myself to code X'40' instead of C' ', so that was how I tested. Then this morning I reaslised I'd not bothered to post the results, so just copied TS's stuff and re-arranged, so untested code, with the X'40' as in the original.
All now clear. The X'40' in 40 bytes looks for X'40' and 39 binary zeros. The C' ' looks for 40 spaces. The X'00' looks for 40 binary zeros.
EDIT:
I've updated the original to avoid confusion. |

Now, you've done it . . . Everyone will be reading manuals and not asking us to do 
Good catch!

Hi,
another way to code this could be
| Code: |
SORT FIELDS=COPY
OMIT COND=(1,20,SS,EQ,X'00',
OR,1,20,SS,EQ,X'40')
|

Hi Dick,
My input records either will have all X'40' or all X'00' not a mixture of both. So I had 3 records with 40 length and one record had value, one record had all X'40' and one record had all X'00'. When I used the OMIT condition given, still I got all 3 records in the output file. |

| Then show the full sysout from your step, and show the three input records, in hexadecimal. |

Because the Sort Control info is incorrect.
Until you do as asked and post the submitted job and the informational messages produced along with the 3 records (in hex), we can't be much help. |

If am not wrong, SS (Substring) would look out for any single spaces to be found, when it does then the particular record would be omitted. |

My mistake, you are correct, I had a number of steps in my job and the SORTOUT statement I looked at did not belong to the above statements.

Yes Gerry I assumed that could be a copy / paste error.
Thank you |

Hello,
So, is the problem with the 3 records now resolved? |
