i make a lot of syntax errors while typing and think a good perl editor will solve my problem
Actually I doubt if it will. Consider all the people on the 'net who type two for to and their for there, etc. All the syntax-checking in the world won't cure that kind of error.
Personally, I use Notepad on Windows (and gedit on Linux). When I make a mistake the compile catches it. When the compile doesn't catch it I learn even more by finding it myself. But if that doesn't suit (and money is no object) try ActiveState's Komodo. I understand it is very good. Or you could try SciTE. It is OK and free. I don't remember where I got it but Google will find it.
The Needs of the World and my Talents run parallel to infinity.
