Reply with quote

I have a problem while sorting a file which has header and detail records. But there are no header identifier as such. It just has fewere fields as compared to detail records.
I have to sort the detail records leaving out the header. Please let me know if there is a way to accomplish it.

Input:

2007052800005020000-------------------->header
20070528055420020009976788---------->details
20070528058160080009965234
20070528045670060009821342
20070528027540030006745434
20070528000300010002342352----------->details

Ouput:
2007052800005020000
20070528000300010002342352
20070528027540030006745434
20070528045670060009821342
20070528055420020009976788
20070528058160080009965234

We are sorting on the detail record starting from the field (9,5) 9 is the starting position and 5 is the lenght.

You can use the technique shown in the "Sort records between a header and trailer" Smart DFSORT Trick at:

You can use that fact to identify the header record, e.g.

20,3,CH,EQ,C' '
