Code to write records to sequential file.
#!/usr/bin/perl#payrollrd.cgi - reads the payroll fileuse CGI::Carp qw(fatalsToBrowser);print "Content-type: text/html\n\n";use CGI qw(:standard);use strict;#declare variablesmy ($name, $stadr, $city, $state, $zip, $jobtype, $jobcode, $payperhr, $salary);open(INF, "<", "payroll.txt")

The while loop in this case is set up to handle all the records in the file. This is coded with while(<INF>) where INF is the name I used to open and close the file. The code in the while loop is enclosed with curly brackets.
