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.

>>> By default, -encode- uses alphabetical encoding, but that
can be overridden.

either

gen gender = cond(sex == "M", 1, 2)
label def gender 1 M 2 F
label val gender gender

or

label def gender 1 M 2 F
encode sex, gen(gender) label(gender)

In press in the Stata Journal 2(3) 2002 is a tutorial
on numbers and strings,
discussing -encode-/-decode-, -real()-/-string()-,
-destring-/-tostring-.
