That ersion of truncate will not work because one cannot execute DDL commands (what "TRUNCATE" is) from PL/SQL. Here is a code snippet that you can try which has the "TRUNCATE" in it:

declare
cursor csr is select 'truncate table '||table_name trunc from user_tables; begin
for c in csr
loop
execute immediate c.trunc;
end loop;
end;
/

This code snippet will truncate all of the tables owned by the user who executes it
and it will work on 8i only ("EXECUTE IMMEDIATE")

If you don't want to do a truncate,

delete from my_table;
insert into my_table values(1,2,3);
commit;

If you are asking about a code,

Probably
Begin

   TRUNCATE ...
   INSERT INTO ....
   COMMIT
END
In practical this is used for temporary tables I don't know if there is any other use.

Anyone who has a good example on a procedure that first deletes all the records in a table and then
does an insert?
