Block-specific comments

Explanatory comments can be inserted at almost any position in an NC program, even at the start of a program. Comments have no effect on the processing of an NC program.

Comments start with a "(". If the comment is extended up to block end, it is sufficient to separate it by "(". For comments within an NC block the corresponding ")" character is also required.

Alternatively, a comment can start with a semicolon ";". This comment type always extends up to block end.

Comments may be of any length. However, the maximum number of characters per block may not be exceeded.

It is possible to nest comments.

Programming Example

Comments in the NC code

Comments on any number of program lines (see Cross-block valid comments) may be made using the special commands #COMMENT BEGIN and #COMMENT END.
