Geez, a guy has an argument with his wife and the whole
world holds it against him. I SAID I was sorry! :-(

Ah, this is a FAMOUS gotcha! See this article:

http://www.dfanning.com/misc_tips/noidea.html

Change this line:

print,where(x.dd eq fix(e_dd))

To this,

print,where(x.dd eq fix(e_dd[0]))

and you will get what you expect. :-)

Cheers,

David
