st: Storing multiple values in a macro

[Malcolm Wardlaw <malcolm@mail.utexas.edu>]

I have a two part question.

The first is, I'm wondering how to store multiple numerical values in a 
macro.  I know how to do it with string variables, but I'm stuck on numbers.

The second is a more general question on a routine I'm trying to run.  
I've constructed a way to do it, but I think it must be terribly 
inefficient.

What I'm trying to do is to merge observations based on a range instead 
of a single value.  The match is one-to-one, but it involves trying to 
match a single date in between a start and end date in another data 
set.  What I did was to loop through each observation in the original 
data set, store the values in a macro, and then `use' only the single 
observation that corresponds to being greater than the first date and 
less then the second.  I then tag that observation with a code and 
append it to a new data set.  This gives me a coded merge-able dataset.

It seems terribly inefficient though.  I have to load one dataset, clear 
it, load another, and then save the results to a third dataset for each 
observation.

Any ideas?
