Hi Suzy,
Just to be clear, are you sure you want to create numeric values? The usual
reason for destringing a variable is that it IS a numeric variable that has
typos which cause it to be regarded as text. Is this is a continuous
variable that does have a numeric (linear etc) relationship. If each of
these string variables represent different disorders, you should have a good
methodological reason for making them numeric. Otherwise, keep them in an
"apples and oranges" arrangement of strings, i.e. diabetes (1003) is not
"one more than" malaria (1002)...
In essence, if you want to use each of these variables as categoricals, they
are fine as is  as strings. You will be able to analyze them as strings, in
a categorical or dummy variable sense.
I may be way off here, but just wanted to make sure you knew you could
analyze them as is.....
Apologies if I am being obvious.
Dan

Subject: st: destringing values led to Stata recoding them as missing
 Dear Statalisters;

 I have seven variables of over 300,000 observations each. Within each
 variable, I have over 2000 different values. These datapoints
 represent specific codes  for example : (72200 = intervertebral disc
 disorder). Within each of these seven variables, there are datapoints
 (values) with dashes or alphabets (Ie: 4109 or V2389). The majority
 of the values though, are purely numeric (23405). I used the destring
 option so that I could analyze the data and Stata treated all those
 datapoints that included dashes and alphabets as missing. Now there is a
 period . where there used to be a value. I have two questions:

 1. Will the restring option restore the datapoints?

 2. How can I successfully "destring" these values so that I can include
 them in my analysis?

 Any help and/or specific code would be very helpful as I am only
 marginally competent with Stata basics.

 Thank you!
 Suzy
