Fenn, See my recent reply to this list regarding o-words and named parameters.
O-words provide programming language looping, testing, and subroutine capabilities that can be wrapped around other gcode. Named parameters let you have natural language names for parameters.

I couldn't find that mentioned in the docs. motion.probe-input see http://www.linuxcnc.org/docs/html/config/emc2hal/index.html > Finally: I'm not necessarily talking about scripting in the place where > currently Gcode is executed. Me either! I don't think gcode would play well with a more free-form language because of its weird syntax requirements. I think of g-code as more of a data format than a programming language. Whether it's human readable or not is irrelevant to the computer, and that's partly why we ended up with such an unreadable mess. Mostly my call for a "macro language" was because I couldn't read any g-code programs with lots of numeric variables. > Well documented script (perl, lua, ruby, python) language bindings to > the movement and IO parts of emc2 would work just as well for me. Definitely - the less wheel-reinventing the better. Getting a real full-featured programming language is a nice side effect! I started thinking about how best to write a Python API for EMC. Didn't get very far, but I think the general idea is sound. In short, I'd rather have the script actually running the machine than just spitting out g-code to feed the g-code parser.
