Im just curios to knwo if there is any 'lookup*' specification in Modify stage that allows a developer to do a string to string decode .

I 've used some lookup specifications that allow you to translate Integers to Strings and vice versa , but is it possible to translate one string value to another ?.

ie if the decode array looks like this
{ 'R'='AUD'; 'X'='SUB' ; 'I'='CAS'; 'Z'='CNC' }

Is there any lookup spec i can use with Modify stage ?
Did i miss something in the documentation if I concluded that it doesnt exist ?

Also - I don't know if this is possible at all , but can a developer create a new Modify stage specification ?

No, there's only integer to string and string to integer.

You can create new specifications; you can't create new functions.
