I meant to say - would the restring option restore my datapoints?

Hi John,
I don't know if this matters but I'm not starting with purely string
variables. I have variables that have datapoints of which some are
string and some are numeric. Also John, would the destring option
restore my original values as now the destringed values are missing....

You might want to consider -encode- instead of destring. Presumably
you're
starting with string variables. Encode will create a new variable with
incrementing value in (I believe) alphabetical order of the original
variable, plus it will make a value label corresponding to the original
string. This is useful if you need to be able to relate the new
variable
value back to the original string.
e.g.
.encode var1, gen(code1)

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
