in reply to Re: header footer
in thread header footer

The file will have 1000s of records each record has its own header and footer. The header and footer can be different for each record. Only thing is that the header and footer are of fixed lenght 50 and 30.

Sry if there was a better way to send a sample file. I copied the same record twice for simplicity sake but they will be different but leaght will be 50 and 30 and each record will have it until the end of the file.

    Just to clarify

    HDR.S287878877.DDDDD.DDDDDDXXXXXXXXXXXXXXXXXXXXXXX

    is the header and

    FTRDDDDDDDDDDFFFFFFFFFFFFFFFFF

    is the footer

      Give your dataset, here's one option:

      use strict; use warnings; local $/ = 'HDR'; while (<DATA>) { chomp; s/\n+$//; print substr( $_, 47, ( length $_ ) - 77 ), "\n" if /\S/; } __DATA__ HDR.S287878877.DDDDD.DDDDDDXXXXXXXXXXXXXXXXXXXXXXX1STR HYTRES NAME PLA +CE DEST GGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGG GGGGGGGGGGGGGGGGGGGG11111111111111111111122222222222222222222222222223 +33333333333333333333333333444444444444444444444444444444444455 5555555555555555555555555555566666666666666777777777777FTRDDDDDDDDDDFF +FFFFFFFFFFFFFFF HDR.S287878877.DDDDD.DDDDDDXXXXXXXXXXXXXXXXXXXXXXX1STR HYTRES NAME PLA +CE DEST GGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGG GGGGGGGGGGGGGGGGGGGG11111111111111111111122222222222222222222222222223 +33333333333333333333333333444444444444444444444444444444444455 5555555555555555555555555555566666666666666777777777777FTRDDDDDDDDDDFF +FFFFFFFFFFFFFFF
