PascalDE (pas-cal-dee) is a code editor/Integrated Development Environment (like Visual Studio or Notepad++) targeted at the Pascal programming language. Written in C# WPF, the code editor features syntax highlighting, autocomplete, error checking and compiler integration.

Development took place over the final year of a BSc Computer Science degree at the University of Hull. The Final Year Project includes the software and a 15,000 word dissertation. The project received a 90% grade and the ‘G B Cook Prize in Computing’ award for the ‘Best Project in the Honours Stage’.
