Places a comment in the output.
The output from this command consists of the comment string. This command is similar to C*** except that the comment produced by C*** is more easily identified in the output. Parameter substitution within the comment occurs for every valid expression delimited by percent (%) signs. Enclosing such an expression in single quotes prevents parameter substitution.
Another way to include a comment is to precede it with a ! character (on the same line). The ! may be placed anywhere on the line, and any input following it is ignored as a comment. No output is produced by such a comment, but the comment line is included on the log file. This is a convenient way to annotate the log file.
This command is valid anywhere.
