Subject: substr passing null...
From: nathanael@gnat.ca ("Nathanael D. Noblet")

Hello,
   I just have a question, often there are 'optional' parameters to 
functions, I've always thought that most of the time I could pass null 
to these if I wanted to leave one empty. This has as far as I can tell 
always worked except recently I was using substr(). If I pass null to 
the third param, I get nothing back. Isn't passing null the same as not 
passing anything? Is this a bug? Or is my logic flawed?
