Re: st: RE: local variable and indexing into a variable

thanks, that makes sense, but is there a general way to refer to the value specifically?  The 
reason I ask is because I have other statements that look like:  scalar `var'_scalar=`var'[_n] 
that aren't as easy to replace in the way suggested.
thanks,
florence
