Note however that the -encode-d variable is most unlikely to be suitable for regression unless you treat it as a factor variable (Stata 10 and earlier: turn it into a set of indicator variables).

-destring- is for variables where the values are numbers
which happen to be stored as strings. As A, B, and R
aren't numbers it will tell you that it won't work.
What you want is -encode-:
*------- begin example --------
clear
input str1 prof
1
2
a
b
end
list
encode prof, gen(profnum)
list, nolab
*------- end example ----------
