Could someone tell me what is wrong withthis function

This is almost a copy / paste from Bruce Momjian's book :
<snip>
create function trigger_iso_code_2_uppercase()
returns opaque
as 'BEGIN
if new.countrycode !~''^[A-Za-z][A-Za-z]$''
then raise exception ''ISO-code are excepted to be uppercase
letters.'';
ENd if;
new.countrycode=upper(new.countrycode);
new.countryname=initcap(new.countryname);
end;'
language 'internal';
</snip>

but I get the following :

<snip>
ERROR: ProcedureCreate: there is no builtin function named "BEGIN
if new.countrycode !~'^[A-Za-z][A-Za-z]$'
then raise exception 'ISO-code are excepted to be uppercase
letters.';
ENd if;
new.countrycode=upper(new.countrycode);
new.countryname=initcap(new.countryname);
end;"
</snip>

Please note that I logging as postgres
