Posted: Thu Jul 22, 2004 10:18 am Post subject: copying a portion of a file
Hello,
I have a report which has both the detailed records and the summary records. I want to copy the summary records along with the header into another file.
To give an idea, the report has,
Report-id Title Date
page-num
header1
header2
-----------------------------------------------------------------
detail1
detail2
detail3
-----------------------------------------------------------------
Report-id Title Date
page-num
header1
header2
------------------------------------------------------------------
Summary for report:
Summary1
Summary2
grand total
Now, I want to use sort, preferably syncsort, to write the summary portion of the report into another file.
What would the best way be? I am thinking on the lines,
1. get the line number of the record having 'Summary for report' - as this has a fixed position always. Lets say it is 'n'
2. subtract 5 lines to get the line number of the previous header record
3. use SKIPREC=n-5 or using STARTREC and ENDREC
I am not sure if I can do an arithmetic operation in the SKIPREC statement.
Any ideas as to how good this is? or any other alternatives?
Regards

vallish,
Everything you asked for is achievable. Let me know the following details.
1. What is the LRECL & RECFM of the input file
2. What is the position of the string 'Summary for report'?
3. post a sample of input and expected output. I was confused with your logic of subtracting 5 from record number.

1. LRECL = 132, RECFM=FB
2. The position of 'SUMMARY OF REPORT' is 1
3. Sample of input:

The solid lines '__' are present in the report and '----' indicates page breaks.
The reason why I thought of the logic to subtract 5 lines was, I want to copy the header record for that portion of the report too along with the summary details into the new file. Makes sense?

Valish,
The following JCL will give you the desired results. If you want the header record for the summary page, you actually need to subtract 6 from the record no: of "summary report"
A brief description of the job. The first copy operator takes in the input report file and adds a seqnum to all the records. This is the record no: of each record. Now using include on outfil we select the "summary report" record and create dynamic control cards.
The next copy step uses this dynamically created control card and copies the desired records to the output file.
Code:
//STEP0100 EXEC PGM=SYNCTOOL
//TOOLMSG DD SYSOUT=*
//DFSMSG DD SYSOUT=*
//IN DD *

Sorry! I found the mistake with the INCLUDE statement. I corrected that.
Now I get an error with OUTFIL statement,

Can I not edit my post? I wanted to delete the earlier reply. _________________ If you're not failing every now and again, it's a sign you're not doing anything very innovative.

vallishar,
In your previous post you mentioned that your input file is FB and is 132 bytes in length.
Now you are saying that it is FBA and the LRECL is 133. If that is the case then the string "summary report" actually starts from pos 2. so change your include condition to

Also, In the output can I replace the PAGE:3 to page:1 by overriding it? _________________ If you're not failing every now and again, it's a sign you're not doing anything very innovative.

I am still not very clear about the second OUTREC. Can you please explain?
Sure can.We are creating a dynamic control card CTL2CNTL. let us say we have a file of 100 records and we want to copy from 50 record onwards. For achieving this we Usually code(one of the n number of ways)
Code:
OUTFIL STARTREC=50
I am doing the same over here also. I am just writting to a DD name OUT. once we found the record no(with include cond), we are subtracting 6 from the record no.
80:X is used to pad spaces to the 80th byte after writting the other outrec fields.
So basically the output will look like this
Code:
OUTFIL FNAMES=OUT,STARTREC=00000020
C' OUTFIL FNAMES=OUT,STARTREC=', means write a text of OUTFIL FNAMES=OUT,STARTREC
+6,SUB,133,8,ZD means subtract 6 from the value at 133 which is of 8 bytes long and
EDIT=(TTTTTTTT) means print out the result after the arthimetic operation is complete
80:X) means pad spaces to the 80th byte.

If I have to use DFSORT instead of SYNCSORT what changes should i do?

Sure can. we use CHANGE parm to change the page number. if the position 2 has the value of PAGE we change the value in the bytes 7 thru 4. I assumed the page number can go upto a max of 9999 pages. Change your control cards to the following.
Why should it be 80 bytes in the control card, though we are having the record length as 133?
The SYSIN data set(control cards) usually resides in the input stream; however, it can be defined as a sequential data set or as a member of a partitioned data set.
The data set must be defined with a RECFM of F or FB. The LRECL can be 80, or more (when valid). If the LRECL is greater than 80, DFSORT will use the first 80 bytes of each record.
check this link which explains in detail about the control cards(sysin) dataset
I changed it to,
OUTREC FIELDS=(1,114,115,5,CHANGE=(13,C'PAGE:',C'PAGE: 1'),
NOMATCH=(115,13),128,4)
since the position of the page was at 115.
What difference will it make if we use or don't use the FIELDS parameter? _________________ If you're not failing every now and again, it's a sign you're not doing anything very innovative.
