eliminate dupes and sum selected records

Postby dgrimsley » Fri Jul 23, 2010 7:25 pm

I have a VB file records are 500 bytes long.

I have created a 4 step process that works but I would like to know if there is a way to combine the steps into 1 or even 2 steps?

Step 1 sums the two amounts needed for the '30' type records where position 39 is greater than 50. There are other '30' type records where position 39 is less than 50 that I do not want to touch.

//SORTIN DD DSN=file1in
//SORTOUT DD DSN=file1out
//SYSIN DD *
SORT FIELDS=(5,51,CH,A)
INCLUDE COND=(39,2,BI,GT,50,AND,54,2,CH,EQ,C'30')
SUM FIELDS=(105,6,PD,111,6,PD)

Step 2 eliminates all dupes of the '20' records where position 39 is greater than 50. There are other '20' type records where position 39 is less than 50 that I do not want to touch.

//SORTIN DD DSN=file1in
//SORTOUT DD DSN=file2out
//SYSIN DD *
SORT FIELDS=(5,51,CH,A)
INCLUDE COND=(39,2,BI,GT,50,AND,54,2,CH,EQ,C'20')
SUM FIELDS=NONE

Step 3 pulls off all records who did not get selected in either of the above two step position 39 is less than 50

//SORTIN DD DSN=file1in
//SORTOUT DD DSN=file3out
//SYSIN DD *
SORT FIELDS=COPY
INCLUDE COND=(39,2,BI,LT,50)


Step 4 combines and sorts the three datasets together

//SORTIN DD DSN=file1out
// DD DSN=file2out
// DD DSN=file3out
//SORTOUT DD DSN=file4out
//SYSIN DD *
SORT FIELDS=(5,32,CH,A,37,2,BI,A,39,2,BI,A,41,3,CH,A,
44,4,BI,A,48,4,BI,A,52,2,BI,A,54,2,CH,A)
RECORD TYPE=V,LENGTH=(500)

You need to tell us more about what you're trying to do exactly rather than the steps you used to do it.

Please show an example of the records in your input file (relevant fields only) and what you expect for output. Explain the "rules" for getting from input to output. Give the starting position, length and format of each relevant field (remember that for a VB file, the RDW is in positions 1-4 and the data starts in position 5). Give the LRECL of the input file.

Also, run this job and show the //SYSOUT messages you receive, so I can see what level you're at:

//S1    EXEC  PGM=SORT
//SYSOUT    DD  SYSOUT=*
//SORTIN DD *
RECORD
//SORTOUT DD DUMMY
//SYSIN    DD    *
    OPTION COPY

By level do you mean V1R10?

Lrecl is 500

col 39 (35+4) is numeric and if it is greater and 50 and col 54 (50+4) is 30 then I want to summerize the two amounts in col 105 (101+4) this is 6 PD and sum 111 (107+4) this is 6 PD getting me down to one record for each set of (>50 and eq 30 records).

col 39 (35+4) is numeric and if it is greater and 50 and col 54 (50+4) is 20 (i only included 20 in the original steps), 40 or 50 then I want to eliminate all dupes and keep just 1 record for each set of (>50 and eq 20, >50 and eq 40, >50 and eq 50)

Examples below have 01 or 51 in col 39 and 10,20,30,40 or 50 in col 54. col 105 (101+4) = 1.22 and 2.22 col 111 (107+4) = 2.00 and 4.00.

Results needed: All 01 (col 39) records left unchanged. Combine the two 30 (col 54) records with 51 (col 39) and only 1 record each ot the 20, 40 & 50 (col 54) with 51 in col 39.

No, I mean PTF level. Please run the job and show the //SYSOUT messages as requested.

Well, you could combine them into one step using ICETOOL with four operators, but I suspect what you really want is to combine them into one pass over the input file and I don't see a way to do that.
