    " So well done, CoSy has stimulated me into trying to learn K "


    Arthur Whitney's K is by many measures one of the most powerful programming languages .
    K.CoSy turns it into an interactive "NoteComputing" environment .

      Highest value use :
    • Consultant , Analyst   Notebook
    • Rapid Quantitative ( particularly Financial ) Modeling
      Requisite ablities :
    • Remembering function keys .
    • Grasping great generalities .
      Recent uses :
    • Diary / Log   with Ledgers
    • HTML Preprocessing view source of this page for examples
    • Screen Scraping ( converting data copied from web pages using ctrl-c , HTML table extraction
    • Portfolio Analysis
    • Email file pre-examination
      Examples from K.CoSy :
    • Color Pallet Widget  Something a little less boring than ledgers
