[Gambas-user] Question on Class.Load

[Ian]

Merci Fabien,
That solution worked very well.

I had thought that you only needed to export classes when using them for 
a component ?
(from the Gambas Wiki on Components - Which is the only reference I can 
find to exporting classes.)

One other question.
So what would Class.Load be used for ?

Ian.
