add one method

[Silvio.Falconi]

to modify a method of a class we use OVERRIDE METHOD
but if I wish add a method "on line" on a class How I can make ?

[rhlawek]

EXTEND CLASS <ClassName> WITH [MESSAGE <MessageName>] METHOD <FunctionName>
EXTEND CLASS <ClassName> WITH MESSAGE <MessageName> INLINE <expression>
EXTEND CLASS <ClassName> WITH DATA <MemberName> [PERSISTENT]

[Silvio.Falconi]

what mean for MessageName
I must add a new function to a class
EXTEND CLASS TXXX WITH [MESSAGE <MessageName>] METHOD Myfunction()
