Abstract: A method for programming and executing a computer program in an immersive sual programming environment, i.e., virtual reality environment, includes steps for assembling data objects and algorithmic components selected from a set of prefabricated virtual components to construct the computer program, compiling the computer program, and executing the computer program by initiating sequential flow of data objects through the algorithmic components. According to one aspect of the invention, the compiling step is performed while providing visual and audio clues to a user in response to a determined compiler error; the clues indicate the location and nature of the detected compiler error. Additionally, the executing step permits the flow of data objects and the interaction among the data objects to be visually displayed to the user. An apparatus suitable for performing the program and execution of a computer program in a virtual reality environment is also described.
