How to add a method via a method?

Hello, I want to write a message with a String-argument,

which adds a new method to MyClass:

---------------------------------------------------------

aMethod: 'MyClass'

---------------------------------------------------------

This is what I wrote for aMethod:

---------------------------------------------------------

aMethod: myClassWhichExist
"comment stating purpose of message"

myClassWhichExist compile: 'myMethod
"comment stating purpose of message"
| h |
h:= ''Hello''.
^ h.' classified: 'delete'

---------------------------------------------------------

I get the following error message:

---------------------------------------------------------

ByteString(Object)>>error:

error: aString
"Throw a generic Error exception."
^ Error new signal: aString

---------------------------------------------------------

I understand that the class name 'myClassWichExist' as string-argument doesn't go along with the compile-message. But to what do I need to convert the string-argument to make it work?

Many thanks in advance for your answers.

Olitizia
