And when all else fails, dark corners of the Source. I think I learned about how the $|-- trick works by having a look at the bits of source (mg.c?) that japhy pointed out; I had heard that it worked but didn't know why, and since perlvar didn't tell me anything specific enough, I RTFS. Upon reading the bits of code that get and set the value of $|, I was enlightened (after thinking a little about it). Cheers, Philip
