Scott:

I don't understand the difference between p4 and p5. I see p6 is under development. If I try it, should I use:

Pascal-P4 is a Pascal subset. Pascal-P5 is full ISO 7185. Pascal-P6 is an extended Pascal. P5 is 1.3, so yes, pascal-p5_1_3.tar.gz.

Ok, thanks! I got https://sourceforge.net/projects/pascalp5/files/pascal-p5_1_3.tar.gz/downloa... There is no mention of macOS in the README. The README says:

The full instructions for running and setting up the P5 compiler/interpreter have all been incorporated into the document:

doc/the_p5_compiler.docx

Which is a Microsoft Word document, 2007 or later. it is also available in the formats:

doc/the_p5_compiler.pdf Adobe Portable Document Format. doc/the_p5_compiler.html Web page format. doc/the_p5_compiler.doc Word 1997-2003 format.

Please consult one of these documents for full instructions on how to use P5.

But that's not true. The doc/ diretory only contains: The_Programming_Language_Pascal_1973.pdf basic.docx iso7185rules.html the_p5_compiler.docx The_Programming_Language_Pascal_1973.pdf is great to have a copy of! I used libreoffice to convert to pdf: /Applications/LibreOffice.app/Contents/MacOS/soffice -env:UserInstallation=file:///tmp/schneidt.lico --headless --convert-to pdf basic.docx

2 Beta software warning p5 Basic is beta software at this time (version <1). It should not be considered reliable for production use.

Oh my. Looks like your documentation may be out of date. Is this still beta despite version > 1? Convert the other docx: /Applications/LibreOffice.app/Contents/MacOS/soffice -env:UserInstallation=file:///tmp/schneidt.lico --headless --convert-to pdf the_p5_compiler.docx This one is dated August 29, 2014 and on page 14 it says:

Is P5 a sueable compiler for real applications? I would assert that it is not.

That's no good!
