Subject to some limitations Finexec scripts can be used in the J Playground. Calculators are NOT available in the J Playground. Option 1 Just copy a source script from the Finexec website library and paste into the J Playground Edit window. Then run all lines. Option 2 Download a script from GitHub to the J Playground Edit window eg: openscript 'https://raw.githubusercontent.com/WilliamSzuch/finance_finexec/master/basicfinance/simple.ijs' Option 3 Install Finexec as an addon in the J Playground. Run the following sentence in the J Playground to install the Finexec addon: install 'github:WilliamSzuch/finance_finexec' (*** This may take several minutes ***) Check the install: dir '~addons/finance/finexec' Then run: load 'finance/finexec' An individual script can be loaded eg: load '~addons/finance/finexec/basicfinance/simple.ijs' Use the Finexec website Library to view the scripts and documentation.
