ah yes -- the simple elegant solution

local model `model' 

strips leading & trailing blanks.  thanks richard.

by the way, removing the = sign does not work:

local model trim("`model'")

returns this:

. di "`model'"
trim(xxx)

where xxx is what was in `model'

thanks.
sean.

How about just

local model `model'

I believe leading and trailing blanks get striped that way.
