• (send a-drscheme:unit:frame get-definitions-text) -> (instaceof (derivedfrom drscheme:unit:definitions-text%))

  This text is initially the top half of the drscheme window and contains the users program.

  This text defaults to a text% object, but if you change drscheme:get/extend:extend-definitions-text procedure, it will use the extended class to create the text.
