Betreff: st: var already defined problem

The '______ already defined' error (r(110)) is usually not a problem  
for me; I just start with a new variable to define or drop the  
existing one.  BUT how can I find what the problem is when I'm looping  
through unique values of a variable?

I'm still working on some spatial analysis and when I create my  
haversine variable (with the option of that name in the -vincenty-  
command) in the forvalues loop I get the error message just  
referenced...and I'm not doing anything esle in the code that is  
demanding a change on this new distance variable.

Thanks for your help,

Diego
