The Register Script

So, now that we have subroutines for reading and storing the various kinds of files we need to manipulate, we’re ready to create the CGI scripts that our users will use to register on the site. Since the reading and writing subroutines will need to be shared by both the registration script (register.cgi) and the verification script (verify.cgi), we’ll put those routines in a separate module file (Register.pm) that each script can pull in with a use statement.

Example 19-2 shows the finished Register.pm module.
