In computer programming, the semicolon is often used to separate multiple statements (for example, in Perl, [32] Pascal, [33] and SQL; [34] see Pascal: Semicolons as statement separators). In other languages, semicolons are called terminators [5] and are required after every statement (such as in PL/I, [35] Java, [36] and the C [37] family).
newline terminated, separated by semicolon or comma (semicolon – result of receding statement hidden, comma – result displayed) MUMPS a.k.a. M newline terminates line-scope, the closest to a "statement" that M has, a space separates/terminates a command, allowing another command to follow Nim: newline terminated Object Pascal

The comma operator separates expressions (which have value) in a way analogous to how the semicolon terminates statements, and sequences of expressions are enclosed in parentheses analogously to how sequences of statements are enclosed in braces: [1] (a, b, c) is a sequence of expressions, separated by commas, which evaluates to the last expression c, while {a; b; c;} is a sequence of ...
"A comma goes before 'and' or 'or' in a series of three or more: Sn, K, Na, and Li lines are invisible." Plain English Handbook, Revised Edition (McCormick-Mathers Publishing Co., 1959), § 483, p. 78 "Use commas to separate the items in a series of words, phrases, or short clauses: The farmer sold corn, hay, oats, potatoes, and wheat."
Semicolon insertion is a feature of BCPL and its distant descendant Go, [8] though it is absent in B or C. [9] Semicolon insertion is present in JavaScript, though the rules are somewhat complex and much-criticized; to avoid bugs, some recommend always using semicolons, while others use initial semicolons, termed defensive semicolons, at the ...
Another, more subtle, difference is the role of the semicolon. In Pascal, semicolons separate individual statements within a compound statement; instead in C, they terminate the statement. In C, they are also syntactically part of the statement (transforming an expression into a statement). This difference manifests mainly in two situations:
