"This program was working for years."

I doubt it, somebody changed something

"I have used CGI::Search"

even if you meant CGI::Switch, that has nothing to do with "Switch" the way you used it. CGI::Switch was a way to replace the $query=new CGI; statement you have somewhere. my $query = new CGI::Switch; "Per default the new() method tries to call new() in the three packages Apache::CGI, CGI::XA, and CGI. It returns the first CGI object it succeeds with." http://search.cpan.org/~chips/perl5.004/lib/CGI/Switch.pm. CGI::Switch has nothing to do with how the word "Switch" was used here. If you have some sort of versioning system i would go back and look at what existed in the past.

My bet is that once there was a colon after Switch, or what @haukex noted about a Switch subroutine somewhere Re^5: Switch.pm Failure

A lot of places ive worked that dont have versioning systems ive created a simple program to make a new backup copy of production code everytime the modified date changed. And everytime someone came to me saying "It stopped working and i didnt change anything" i was able to go into this archive and show them the change THEY made that made it stop working now.
