You want to -set trace on- which enables you to see what Stata makes of your
commands.

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
