If you are trying to define a class in a method, this technique is not permitted. You must define the class external to the form like this:

set procedure to myclassprg.prg additive
this.newobject('myObject','myClass')
...

And you must have an external definition like:

define class myClass as SomeBaseClass
,,,
enddefine
