Most languages support multi-line block (a.k.a. stream) and/or single line comments. A block comment is delimited with text that marks the start and end of comment text. It can span multiple lines or occupy any part of a line. Some languages allow block comments to be recursively nested inside one another, but others do not.
If the first character of a line, including indentation, is an asterisk (*) the whole line is considered as a comment, while a single double quote (") begins an in-line comment which acts until the end of the line. ABAP comments are not possible between the statements EXEC SQL and ENDEXEC because Native SQL has other usages for these characters.

The codes 000 and 001 ...

The shebang line is usually ignored by the interpreter, because the "#" character is a comment marker in many scripting languages; some language interpreters that do not use the hash mark to begin comments still may ignore the shebang line in recognition of its purpose. [9]
Some INI dialects furthermore allow use of the number sign (#, ASCII 0x23) to denote a comment, mirroring Unix shell comments. Some INI dialects but not all allow a comment on a key-value pair line or section line (called in-line comment), where some require whitespace separating the value or section closing bracket from the comment. The number ...

Fish (or friendly interactive shell- stylized in lowercase) is a Unix-like shell with a focus on interactivity and usability.
