How to create thousands of sql scripts easily?

Question

Hello,
I would like to create thousand of scripts as following:
insert into table tb_test('aaa');   update table tb_class( set nm = 'aaa');
insert into table tb_test('basd'); update table tb_class( set nm = 'basd');
insert into table tb_test('asdfa');update table tb_class( set nm = 'asdfs');
insert into table tb_test('xxxyy');update table tb_class( set nm = 'xxxyy');
Is there any simple way to generated those scripts automatically? I am thinking of :
    define var_str = ('aaa', 'bbb', 'asdfd',...'xxxyy');
    select 'insert into table tb_test(' || var_str || '); update table tb_class( set nm =' || var_str || ');'
    from dual;
Then how do I generate those scripts from the var_str?
Thanks,

I have more than 5000 parameters in a text file as followings, which can be opened by notepad or excel:
'aaa',
'basd',
'asdfs',
'xxxyy'
Ok, so assuming this is a 1-off event, use Excel.
Setup a quick formula to turn each into a proc call:
[edit] if the values are in column "A", then in column "B", you could do:   =concatenate("p_proc('", a1, "');")
then copy that formula down.
[/edit]
p_proc('aaa');
p_proc('basd');
etc.
Then setup a little p_proc as Frank described. (and please, use a WHERE clause on that update ... or you're going to destroy some data )
Then copy past those commands into a routine that ends up looking like:
declare
procedure p_proc ( in_value )
  is
  begin
      -- Frank's code goes here
  end;
begin
   -- proc list goes here
  p_proc('aaa');
..... etc.
end;
That's 1 very primitive way to do it.
If you need to reproduce this in future, you may want to consider loading that list of parameter values into a table, then you can do some more funky things. *shrug*
