Listed below are all of the tasks on Rosetta Code which have been solved using DUP.
Your Help Needed
If you know DUP, please write code for some of the tasks not implemented in DUP.

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.
