Sort question

Postby r rudram » Wed Dec 21, 2011 3:20 pm

Hello,

I have a 3700 byte data file as follows (File A) and a VSAM lookup file (File B) - 1000 bytes. File B has the key field in column 1-11.

The rules -

The lookup file B will be used to read File A, and if there is a match of the File B key in File A, I will need to eliminate those records alone from A.
File A can contain these key values in multiple (specific) columns within the same record. I need to scan for the presence of these key values in those columns and reject the records with a matching key (dump to file) and retain the unmatched ones from File A in its entirety with no change to file structure.

File A can contain spaces for the columns being validated.

Examples provided below - (See attached spreadsheet if alignment problems in the post)

Input file A - Several columns omitted below for illustration only, does not depict all columns of File A, also a few more columns can contain the dups, not shown here.

Prod# Name CODE(1) CODE(2) CODE(3) CODE(4)
(Pos 200:11) (Pos 300:20) (Pos 500:11) (Pos 600:11) (Pos 700:11) (Pos 800:11)

55587656700 Smith 00179195732 00656566454 00179009330

Is there any way I could use splice for this or any other method with ICETOOL? Any pointers are appreciated!

Thank you!

Why is Jane in your output?

it would be better to use a more intelligent title,
a poor title usually implies carelessness and a poor question
people willing to answer will most usually skip such topics

OK You asked for it!
Why is Jane in your output?

IMHO the problem is not Jane being there, it' s TARZAN that' s missing :geek:

Yes, I produced a very good example of a thoughtlessly-worded question :-)

A better attempt.

Why is your second output record included in the output, when it not only matches the reference file but matches it with two different values, or is this an implicit part of the logic, in which case please make it explicit?

My apologies - The second record in the output file should have been shown in the "matched" file.
Thank you for pointing to the subject line- I've revised it to something more meaningful.

r rudram,

It is NOT clear as to what the output is. If I understand you correctly, your vsam key needs to be looked in 5 places of the input file Prod#,CODE(1),CODE(2),CODE(3),CODE(4). if it is found in any of these values then reject that record or else write the record as is to unmatched file from fileA

Post a better examples of input and output and also run the following job and show us the complete sysout which will help us determine the level of DFSORT you have

//STEP0100 EXEC PGM=SORT     
//SYSOUT   DD SYSOUT=*       
//SORTIN   DD *             
//SORTOUT  DD SYSOUT=*       
//SYSIN    DD *             
  SORT FIELDS=COPY
