Peter Newman 8 January 2005 ------------------ Unified Programming Language
IMHO cores are the root of all evil (in programming languages). So UPL doesn't have one.
Instead, every data type and command/function is a stand-alone, script level programmer selectable entity.
In other words, every programmer can create their own personal programming language - by selecting the data types and commands/functions they want.
These are selected by editing UPL: The Bootstrap File.
