Flow Control
Traditional procedural programming languages typically require programmers to define an explicit "flow of control" at every stage in their programs. The Wolfram Language provides standard flow control primitives, with various symbolic extensions—though its higher-level programming paradigm usually frees programmers from having to specify the details of flow control.
Return — return from any function
Break, Continue — break, continue in procedural looping constructs
Goto, Label — largely obsolete explicit procedural flow control
Throw — "throw" any expression to be "caught" by a surrounding Catch

Interrupt ▪ CheckAbort ▪ AbortProtect ▪ PropagateAborts
TimeConstrained, MemoryConstrained — run with constraints
Pause — pause for a specified time
