The Exam Reference Language Interpreter
This is a full implementation of an interpreter for the OCR exam reference language (OCR ERL) – it helps GCSE Computer Science students practice their programming by running it online on the website. There’s even a line-by-line debugger!
OCR ERL is similar to pseudocode – an idealised programming language used in the latest OCR Computer Science exam syllabus. You can use this site to test out your OCR ERL programs and see how they would actually run.
OCR ERL is designed by and owned by OCR and forms part of their J277 Computer Science GCSE specification. This site is not associated with OCR – it was coded by John Williams and is offered as a service to the GCSE Computer Science student community.
