Exemplary embodiments enable debugging executable code using a debugger in a computational device that provides a programming environment including a presentation layer. For example, an exemplary method includes providing a first marshalling function that receives a portion of information manipulated by the executable code and produces a presentation layer representation of the portion of the information. The presentation layer representation is compatible with a debugger that debugs the executable code. An exemplary method also includes debugging the executable code to produce a presentation layer representation of the portion of the information with the first marshalling function so as to display the presentation layer representation of the portion of the information to a user via a display device. The debugging also includes modifying the presentation layer representation of the portion of the information to produce modified information for use by the executable code, a device, or a user.
