Hi,

I need to crop a VB file where I need to delete some columns, but the header and trailer record should not be changed in the output file. The trailer record can be identified using a key and header is always the first record. Is it possible in Sort?

I try to explain by example(Input and output are VB file):-

Input File:-

123456789HEADER
123456789RECORD1
123456789RECORD2
123456789RECORD3
.............................
.............................
123456789RECORDn
123456789TRAILER

Let say I need to detele columns 4 to 9.

Output File required as:-

123456789HEADER
123RECORD1
123RECORD2
123RECORD3
.............................
.............................
123RECORDn
123456789TRAILER

Thanks,
Manu

Manu,

You can use a DFSORT job like the following to do what you asked for:

Code:

//S1    EXEC  PGM=SORT
//SYSOUT    DD  SYSOUT=*
//SORTIN DD DSN=...  input file (VB)
//SORTOUT DD DSN=...  output file (VB)
//SYSIN    DD    *
  OPTION COPY
  INREC IFTHEN=(WHEN=(14,6,CH,NE,C'HEADER',
     AND,14,7,CH,NE,C'TRAILER'),
    BUILD=(1,7,14))
