I have the following perl script that reads a fixed-width file and
replaces values in various sections of the file.
-------------------------------------------
open (IN, '< in.txt');
open (OUT, '> out_test.txt');
while (<IN>) {
chomp;
$first_section = substr $_, 0, 381; # extract the first
section of the record
$facilityno = substr $_, 381, 10; # extract the facilityno
field
$second_section = substr $_, 391, 1056; # extract the
second section of the record
$requestor_section=" " x 500;
# $requestor_section = substr $_, 1446, 499; # extract requestor
section of record
$third_section = substr $_, 1946, 4748; # extract third
section of record
# print out the file with changed facilityno value ...
print OUT "$first_section$\0039007300$\$second_section$\
$requestor_section$\$third_section\n";
}
close (IN);
close (OUT);
------------------------------------------------
I want to place an "if...then" condition on the $facilityno value; such
that if the $facilityno value = 0000000000, delete the record (e.g.,
don't print out that row).
Any advice is very much appreciated.
