What does the semicolon symbol represent in CNC machines and basic addresses?
A. It is used for comments and messages in front of the program. B. It is used to skip program blocks. C. It is used to indicate program number for ISO standard. D. It is used at the end of each program block.
A semi-colon is typically used in a CNC machine or basic address to indicate a line to be ignored. This use of the semicolon can vary from machine to machine, so a manual should be consulted first. However, it can also be used to denote the end of a program block, as the previous answer here as indicated.
When used in this capacity, it is typically only a representation of said end-of-block. There is usually another character used in the code for this purpose. That said, the semi-colon isn’t the only character that can be used in this capacity. The asterisk () and the dollar sign ($) have been used in this capacity. It all depends on what systems are being used to write the CNC coding.
