Listed below are all of the tasks on Rosetta Code which have been solved using ObjectIcon.
ObjectIcon is a virtual machine. Other virtual machines.

Object Icon is an object oriented variant of Icon based on an early fork of the Unicon Project developed by Robert Parlett (one of the co-authors of the Unicon book). Some of the distinguishing characteristics are:

  • a richer set of object oriented keywords
  • support for unicode characters
  • replacement of the I/O support with a package
  • differences in keywords

In April 2023, Robert Parlett's Subversion repository at was migrated to Git by an advocate of the language, and given primary hosting at to encourage forking and wider use.
