I have a requirement to create a header and trailer record in a file that has only detail records. The header has some static information and two dates. Date 1 is the beginning date which comes from the first record (position 98 - 107) in the file and the ending date which is in the last record (position 98 - 107) of the file. The trailer record has some static data and a record count of the number of detail records + 2 (includes the header and trailer). Any help would be appreciated.
Thanks

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. Give the RECFM and LRECL of the input files.

Also, run this job and show the //SYSOUT messages you receive, so we can see which sort product/level you have:

Code:

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

This is the sort product/level (let me know if you need more info):

ICE000I 1 - CONTROL STATEMENTS FOR 5694-A01, Z/OS DFSORT V1R5

The rules are as follows:

1. all records copied "as is" in the same order from input to output (records fixed (FB) length = 225)
2. in the output file create a header (FB) as follows:
position
1 - 10 "HEADER "
11-14 "DEV1"
15-24 is a date which comes from the first record in the file from positions 98-107
25-34 is a date which comes from the last record in the file from positions 98-107
35-38 "QLPF"
39-225 padded with spaces

Sample header:
HEADER DEV11995-01-012011-05-12QLPF

3. Create a Trailer record (FB)

Position
1-10 "TRAILER "
11-19 record count of #records in file including the header and trailer
20-225 padded with spaces

Sample trailer:

TRAILER 020692380

Here's a DFSORT job that will do what you asked for.

Code:

//S1 EXEC PGM=SORT
//SYSOUT DD SYSOUT=*
//SORTIN DD DSN=... input file (FB/225)
//SYM DD DSN=&&S1,UNIT=SYSDA,SPACE=(TRK,(1,1)),DISP=(,PASS)
//SYSIN DD *
  OPTION COPY
  OUTFIL FNAMES=SYM,REMOVECC,NODETAIL,
    BUILD=(80X),
    TRAILER1=('LAST_DATE,''',98,10,'''')
/*
//S2  EXEC  PGM=SORT
//SYSOUT    DD  SYSOUT=*
//SYMNAMES DD DSN=&&S1,DISP=(OLD,PASS)
//SORTIN DD DSN=... input file (FB/225)
//SORTOUT DD DSN=...  output file (FB/225)
//SYSIN    DD    *
 OPTION COPY
 OUTFIL REMOVECC,
   HEADER1=('HEADER',11:'DEV1',15:98,10,
     25:LAST_DATE,35:'QPLF'),
   TRAILER1=('TRAILER',11:COUNT+2=(M11,LENGTH=9))
/*
