This is good, but not I would say optimal.
Suppose for example your strings really
start with a space in some or all observations.
Suppose you haven't spotted that a few observations
don't follow this pattern.
If so, you will have messed up your data.
Even if not,
replace varname = subinstr(varname, "www.", "", 1)
is a more focused approach to the problem. Yet
another small advantage is that your purpose will
be clearer in do or log files.
