In addition, I advise verifying the leading characters, particularly in the
second (and any subsequent) variables. You want to make sure that such
values as "0010" and " 10" are always the same or are always different, as
appropriate. Sometimes frequencies on a position by position basis are
helpful.

Yes. Basically, + means concatenation
with strings (i.e. string variables or more generally
expressions which are or which evaluate to strings)
on either side.
gen strboth = strvar1 + strvar2
gen strboth2 = strvar1 + " " + strvar2
Also check out -egen, concat()-.
