The return value from a function is provided within the function by making an assignment to an identifier with the same name as the function. [5] However, some versions of Pascal provide a special function Exit(exp); that can be used to return a value immediately from a function, or, without parameters, to return immediately from a procedure.

Go does not follow SemVer; rather, each major Go release is supported until there are two newer major releases. Unlike most software, Go calls the second number in a version the major, i.e., in 1.x x is the major version. [48] This is because Go plans to never reach 2.0, given that compatibility is one of language's major selling points. [49]
Even when the return and forward channels use the same medium, their differences often dictate the use of very different data modulation and coding techniques. For example, in a star radio network, only the central hub transmits on the forward link, so channel access method is a consideration only on the return link.
In this example, two hardware threads are started on the XMOS, running the two lines in the "par" block. The first line transmits the number 42 through the channel while the second waits until it is received and sets the value of x. The XC language also allows asynchronous receiving on channels through a select statement.
In a language with free pointers or non-checked array writes (such as in C), the mixing of control flow data which affects the execution of code (the return addresses or the saved frame pointers) and simple program data (parameters or return values) in a call stack is a security risk, and is possibly exploitable through stack buffer overflows ...
VerilogCSP is a set of macros added to Verilog HDL to support communicating sequential processes channel communications. Joyce is a programming language based on the principles of CSP, developed by Brinch Hansen around 1989. SuperPascal is a programming language also developed by Brinch Hansen, influenced by CSP and his earlier work with Joyce.
Coroutines are well-suited for implementing familiar program components such as cooperative tasks, exceptions, event loops, iterators, infinite lists and pipes. They have been described as "functions whose execution you can pause". [1] Melvin Conway coined the term coroutine in 1958 when he applied it to the construction of an assembly program. [2]
map function, found in many functional programming languages, is one example of a higher-order function. It takes as arguments a function f and a collection of elements, and as the result, returns a new collection with f applied to each element from the collection.
