When you say Stata converted numbers to strings, note that Stata
usually has a good reason for this, namely that you are importing
stuff that is not numeric.

First problem:

Non-numeric characters are easily found in a string variable -strvar-

tab strvar if missing(real(strvar))

The non-numeric characters would stand in the way of the function
-real()-, and so it would yield missing. This tabulation may yield a
long table, but it would usually indicate the problem(s), which may
well be something you can deal with using -destring- options.

Second problem:

Please give an example.
