Simon,

Thank you.  Your suggestion, of course, worked.  Why I oddly thought 
Ruby should split the hash elements into separate lines, but not the its 
array elements, I'll never know! After being up all night, I guess my 
brain just stopped working.

I've seen the acronym yaml around a few times, but short a guessing that 
it means yet another meta language I do not know what it actually does, 
but I will take a look at it as you suggest.

Again, thank you.  I'm awake now!  (:>)

David
