This is a typeset copy of Chuck Moore's unpublished book Programming a Problem-Oriented-Language. This book describes the thinking behind the software that later became Forth.

What I have done:

• Convert HTML to markdown using Pandoc
• Correct spelling mistakes.
• Fix formatting.
• Convert to PDF via LaTeX using Pandoc and memoir package.
• Add a cover page.

To do:

• Convert hand-written drawings to vector graphics using something like ditaa or PGF.
• fix page numbers to start on chapter 1 instead of the title page.
