st: Re: MATA: dynamically generating variable names in MATA

[Kit Baum <baum@bc.edu>]

What you describe below creates variables equal to constants, which  
is not a good idea in Stata. If you want to have a set of scalar  
values taking on specific values, use the scalar command in Stata.  
You can, as others have suggested, do something similar with matrix  
elements in Mata (which, like Stata, is not an acronym). You can also  
use Mata pointers to create a set of temporary variables in Mata.
