Switch statements function somewhat similarly to the if statement used in programming languages like C/C++, C#, Visual Basic .NET, Java and exist in most high-level imperative programming languages such as Pascal, Ada, C/C++, C#, [1]: 374–375 Visual Basic .NET, Java, [2]: 157–167 and in many other types of language, using such keywords as ...

Within an imperative programming language, a control flow statement is a statement that results in a choice being made as to which of two or more paths to follow. For non-strict functional languages, functions and language constructs exist to achieve the same result, but they are usually not termed control flow statements.
The switch parser function, coded as "#switch", selects the first matching branch in a list of choices, acting as a case statement. Each branch can be a value , an expression ( calculation ), or a template call, [ 1 ] evaluated and compared to match the value of the switch.
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
In both C# and Java, programmers can use enumerations in a switch statement without conversion to a string or primitive integer type. However, C# disallows implicit fall-through unless the case statement does not contain any code, as it is a common cause of hard-to-find bugs. [29] Fall-through must be explicitly declared using a goto statement ...
See note about C-like languages; the Else clause of a single-line If statement can contain another single-line If statement. Select« Case» variable Case case_pattern 1 instructions ... «Case Else instructions» End Select: IIf(condition, valueIfTrue, valueIfFalse) Visual Basic .NET: If(condition, valueIfTrue, valueIfFalse) Xojo
To avoid potential bugs owing to the similarity of the switch statement syntax with that of C or C++, C# requires a break for each non-empty case label of a switch (unless goto, return, or throw is used) even though it does not allow implicit fall-through. [16] (Using goto and specifying the subsequent label produces a C/C++-like fall-through.)
