By the way, I am uploading in ASCII mode, not binary.

Then your FTP client or the server is broken, or your file was saved with Mac line endings, but most likely you are NOT uploading in ASCII mode.

Is there any way I can write perl in Textpad without using the -w switch

You can, always, but for CGI scripts you should use strict, warnings and taint mode.

#!/usr/bin/perl -wT
use strict;
