Compiler issues related to iconic visual languages

This research studies the visualization of traditional programming languages. The major problem is how to represent traditional one-dimensional language in a twodimensional paradigm. The focus of this research is compiler issues, traditional compiler theories and algorithms, together with new concepts that are applied in the research. A multi-paradigm programming language environment was created to experiment the theoretical solution. The current target language is C+-I-, but the environment configuration can be applied to other traditional programming languages. In this particular environment, specific attention has been given to the user interface, data structures, parsing, and error handling. This research uses a new approach, and provides some possible solutions in the Visual Programming Language field.
