CNC code syntax is the set of rules and conventions that define how to write and structure CNC code. Syntax rules vary depending on the machine, the controller, and the software used, but they generally include the use of letters, numbers, symbols, spaces, and comments. Syntax errors are mistakes in the code that violate the syntax rules, such as missing a letter, using a wrong symbol, or having an extra space. Syntax errors can cause the machine to malfunction, produce incorrect results, or stop working altogether. To avoid syntax errors, CNC programmers and operators should follow the syntax rules carefully, use a code editor or simulator that can check and highlight errors, and test and debug the code before running it on the machine.
CNC code logic is the way the code controls the sequence, condition, and repetition of the machine operations. Logic flow and structure are important for creating CNC programs that can perform complex and dynamic tasks, such as adapting to different materials, shapes, or parameters. Logic flow and structure are achieved by using commands, functions, and variables that can manipulate the data and the machine behavior. For example, G-code commands can specify the type and direction of the movement, functions can perform calculations and conversions, and variables can store and change values. However, logic flow and structure also present some challenges and limitations for CNC programmers and operators. Some of those challenges include maintaining readability, clarity, and consistency of the code, avoiding conflicts and contradictions between commands and functions, and dealing with errors and exceptions that can interrupt or alter the logic.
CNC code compatibility and standardization are the extent to which the code can run on different machines, controllers, and software without errors or modifications. Compatibility and standardization are desirable for CNC programmers and operators because they can save time, money, and effort by using the same or similar code for different purposes and platforms. However, compatibility and standardization are often difficult to achieve, as there are many variations and differences in the CNC code syntax and logic among different manufacturers, models, and versions of machines, controllers, and software.
Some of these differences are minor and can be easily adjusted, while others are significant and require extensive changes or conversions. To improve compatibility and standardization, CNC programmers and operators should use common and universal codes and formats — such as ISO 6983 or EIA-274-D — whenever possible, and be aware of the specific features and requirements of each machine, controller, and software they use.

My experience is with the Fanuc CNCs, mostly with lathes. Every brand of CNC has differences in their G-code language and behavior. The broad strokes are mostly the same, so you can usually take a program written for machine A and use the part geometry in a program for machine B. The details may change. If you have the same model control, but a different machine builder, M-codes can be different. Also, CNC manufacturer options or machine buildeer made extensions can vary, so you have to watch out for those things. However, you can often reuse the part geometry itself if you are careful. Always test before running!
