I want to comment this matching rule in lex. I don't want to delete it. I just want it commented so anyone sees the lex file later be informed that this part has been commented
<tickPragma_name_1>.
myyyless(0);
BEGIN (0);
how I can do that? I know that I can comment the C code inside the .but I want to comment the whole rule.

You can surround the rule with /* and */, just as in C, but with two major caveats:
Everything needs to be indented by at least one space, including the
/*(and, I believe, the contents).There cannot be any nested comments in the action.
