About the LDPL programming language

LDPL is a very simple (but powerful) open-source programming language designed from the ground up to be excessively expressive, readable, fast and easy to learn. It is mostly written in a series of statements that mimics plain English, in the likeness of [the good parts of] older languages like COBOL, with the desire that it can be understood by anybody.

It's very portable and runs on a plethora of different architectures and operating systems including AMD-64 Linux and Windows, ARMv8 Linux, Android and both Intel and PowerPC Mac OS X (tested from Tiger 10.4 onwards).

It even supports UTF-8 out of the box.
