问题
I want to do following transposing of records into column using SORT (snycsort or DFSORT). It should be scalable to any number of records .Is this possible ?
DE001XYX A
CD100000 B
CD200000 C
DE001KKK A
CD100000 B
DE003ZZZ A
DE001XYX A
CD100000 B
CD200000 C
DE001KKK A
CD100000 B
........
Transpose
DE001XYX CD100000 CD200000 DE001KKK CD100000 DE003ZZZ DE001XYX CD100000 CD200000 DE001KKK CD100000 .....

This is one question which I Favorited and longed to solve it myself for quite some time. After some research & try outs, I've just come up with a solution.
UPDATE: Improvised approach is given below. It solves the problem in 1 pass itself whereas the initial approach took 3 passes.
Improvised approach: No need of 3 passes.

Results in the same output which OP has shown in his/her question.
Initial approach:
Step 1:
I used WHEN=GROUP with BEGIN, END and PUSH parameters.
//JOBNAME JOB ('ACCOUNT NAME'),'TRANSPOSE',
// CLASS=2,MSGCLASS=H,NOTIFY=&SYSUID
//STEP1 EXEC PGM=SORT
//SORTIN DD *
DE001XYX A
CD100000 B
CD200000 C
DE001KKK A
CD100000 B
DE003ZZZ A
DE001XYX A
CD100000 B
CD200000 C
DE001KKK A
CD100000 B
//SORTOUT DD SYSOUT=*
//SYSOUT DD SYSOUT=*
//SYSIN DD *
SORT FIELDS=COPY
OUTREC IFTHEN=(WHEN=GROUP,BEGIN=(12,1,CH,EQ,C'A'),
END=(12,1,CH,EQ,C'C'),PUSH=(14:ID=1))
PUSH=(14:ID=1) means position 14 for 1 is an identifier that increments for each group. Each A indicates a new group regardless of whether the previous group was terminated with C. The identifier is +1'd when a new group is started.
Note: Since we are only allowing one character for the ID, when the ID counter gets to 10, a '0' will appear in position 14. You may also assign more than 1 byte for the ID.
Output from the Step 1:
********************************* TOP OF DATA **********************************
DE001XYX A 1

DE001KKK A 5

******************************** BOTTOM OF DATA ********************************
Step 2: Take the output from Step 1. Modify the position of DE, CD1 and CD2 records based on the three keys A, B and C respectively.

Note: Binary zeros are inserted in between, as place holders so that they can be filled in with data, in Step 3.

More details on SUM FIELDS with Binary zeros:
Binary addition operates on two bit patterns. Let's consider the following records (Hex mode is ON as I would like to show how Binary addition is being performed on the Hex values).
****** ********
000001 DE001XYX
CCFFFEEE
45001787
---------------
000002
00000000
00000000
Hex value of the first byte, X'C4' is being added with the binary zeros in the 1st byte of 2nd record.
C4
+00
--
C4
X'C4' denotes Letter 'D' in EBCDIC
If we change the Binary zero in the first byte to Binary one (X'01'), results will vary.
C4
+01
--
C5
X'C5' denotes Letter 'E' in EBCDIC.
With Binary zeros we can perform SUM FIELDS on Alphanumeric data items (EBCDIC characters a-z, A-Z, 0-9) to group them onto one single record.
