COBOL (/ ˈ k oʊ b ɒ l,-b ɔː l /; an acronym for "common business-oriented language") is a compiled English-like computer programming language designed for business use. It is an imperative, procedural, and, since 2002, object-oriented language. COBOL is primarily used in business, finance, and administrative systems for companies and ...
Brackets are also allowed to be nested inside comments (i.e. #`{ a { b } c } goes to the last closing brace). Ruby. Block comment in Ruby opens at =begin line and closes at =end line. S-Lang. The region of lines enclosed by the #<tag> and #</tag> delimiters are ignored by the interpreter. The tag name can be any sequence of alphanumeric ...
Syntax for comments varies by programming language. There are common patterns used by multiple languages while also a wide range of syntax among the languages in general. To limit the length of this section, some examples are grouped by languages with the same or very similar syntax. Others are for particular languages that have less common syntax.

In Turbo Pascal, directives are called significant comments, because in the language grammar they follow the same syntax as comments. In Turbo Pascal, a significant comment is a comment whose first character is a dollar sign and whose second character is a letter; for example, the equivalent of C's #include "file" directive is the significant ...
In C and C++ short, long, and long long types are required to be at least 16, 32, and 64 bits wide, respectively, but can be more. The int type is required to be at least as wide as short and at most as wide as long , and is typically the width of the word size on the processor of the machine (i.e. on a 32-bit machine it is often 32 bits wide ...
English keywords are retained where C uses punctuation symbols – Pascal has and, or, and mod where C uses &&, ||, and % for example. However, C is more ALGOL-like than Pascal regarding (simple) declarations, retaining the type-name variable-name syntax. For example, C can accept declarations at the start of any block, not just the outer block ...
COBOL uses the syntax WRITE record-name AFTER ADVANCING n Lines., where record-name is the name of the area containing the line and n is the number of lines. Additionally BEFORE ADVANCING can be used or BEFORE|AFTER ADVANCING TOP to skip to the top of a new page. [1]
