RE: Using variables in command substitution

["Dan Luther" <dan@xxxxxxxxxxxxxx>]

Thanks -- this fixed my problem. You have to escape the "|" character, e.g.:

HNAME=(uname -n \| cut -d. -f1)
. . . 

Thank you again for prompt reply!

You're hitting the fact that zsh doesn't split scalar variables
automatically.  See http://zsh.sourceforge.net/FAQ/zshfaq03.html#l18 .

A quick fix for the commands is to use arrays:

ME=(/usr/xpg4/bin/id -un)

etc.
