I think destring would require to have your variable coded as '1' and '2'
already. So either you rename them first:

replace sex="1" if sex=="m"
replace sex="2" if sex=="f"

and than destring, replace

or you could try: 

encode sex, gen(sex2)

This gives you F=1 and M=2, because it's done alphabetically but the rest is
easy to change.

Hello statalisters,

I have a variable in my datasheet, sex which is formatted as str1 %9s.
There are two types either M or F.  I need to convert this so that M=1 and
F=2. How do I do this, or where is a problem similar to this described.  I
have tried using "destring sex, replace" etc but have had no luck.
Thanks for all your help in advance on this relatively simple question.
