Re: Extracting name value pairs from Environment Variables

Have you checked what's in the INPUT hash table?

Try to add Data::Dumper to see what's held in INPUT.

use Data::Dumper;
...
print "Content-Type: text/html\n\n";
print "<HTML><BODY><Pre>\n"
print Dumper(\%INPUT); # insert this after the foreach loop
print "</Pre></BODY></HTML>\n"
exit(0);
...

And see what's held in INPUT. The reason why $address remain undefined is because the hash keys you are looking for might not exist in the hash table.

You are absolutely right, and I thank you for showing me the use of Data::Dumper - I have now added that to my armoury... Once I'd seen that the values were not held in INPUT I looked more closely at the embedded HTML code and found that I had made a mistake in that. When I fixed it `$address` magically appeared. Thanks once again for your help.	[reply] [d/l]
