st: Spelling errors in string variables

[Estrella Gomez <estrellastata@gmail.com>]

Does anybody know how can I check the existence of spelling error in my
dataset? I have two string variables with nearly 1,500,000 observations,
and I would like to check if in some cases there are different names for
the same individual (i.e.: Mexico / Mejico / mexico)

Thank you
