DUP is a Forth-like esoteric programming language invented by Ian Osgood. DUP is a variant/enhancement of Wouter van Oortmerssen’s FALSE language.

Changes from FALSE include:

• Change of operators: DIV (integer division) changed to Forth-like MOD/DIV, new OVER operator etc.
• String output changed to string definition. Output has to be handled separately.
• Return stack is fully accessible and can be manipulated.
• Operator definition and override is possible. Access to full Unicode array of symbols for operator names.

• DUP on Esolangs
