(Possibly?) little-known fact: It's possible to use $ListBuild on the left hand side of the equals sign in a set command to extract multiple list values at once:
set $ListBuild(several,individual,variables) = list
For example:
USER>kill
USER>set colors = $ListBuild("red","orange","yellow")
USER>set $ListBuild(r,o,y) = colors
USER>write r,!,o,!,y,!
red
orange
yellow
USER>set colors = $ListBuild("red","orange","yellow")
USER>set $ListBuild(r,o,y) = colors
USER>write r,!,o,!,y,!
red
orange
yellow

This feature was news to me - I use $ListBuild lists a lot but hadn't come across it until today.
