 Dossy,

you crack me up. i've read this! that's what i don't understand. according to 
it, anIO is optional but when i try the second example it bombs. not very 
optional. maybe i just don't know how to read this correctly but it seems to 
be acting more like:

	dump( anObject [, anIO [, limit=1 ] ] )

what am i missing?

thanks,
