st: string variable

[ncdcta00@uniroma2.it]

Dear statalist,
 I want to convert a string variables(type:  T0274K0VH550101) in   
numeric.  I try to use the commands destring and encode, but with the  
first I din't have any result, while with the second I have this error:
 encode codind, gen(id)
too many values
r(134);
 with destring I have
 destring codind, generate(id) force
codind contains non-numeric characters; id generated as byte
(128147 missing values generated)

exist  another solution?
thanks in advance for your help.
