Good day, Fred:
Thank you for the question. Let’s look at the three parts of your sample document:
- Should computer code numbers be in Nemeth Code (e.g., G40, G42, etc.)? No, I would not put these codes in Nemeth switch indicators.
- Should equations be in Nemeth Code? Yes (including “PITCH = 1/Threads per inch”, “1.0 divided by 8 TPI = .125”, “(1.500-.75)/2 = .375”). I agree that “Z-Axis” does not require Nemeth Code; it is not a math expression.
- Should [line-by-line] computer code be in Nemeth Code? The Guidance for Transcription Using the Nemeth Code within UEB Contexts is not designed to address computer code. UEB is equipped to handle computer notation (See Guidelines for Technical Material, section 17). I would use UEB for computer notation like this.
Thank you again for your thoughtful questions. Please let me know if you have follow-up concerns.
