Both FOR/NEXT and START/NEXT support a user-defined step increment. By replacing the terminating NEXT keyword with an increment and the STEP keyword, the loop variable will be incremented or decremented by a different value than the default of +1. For instance, the following loop steps back from 10 to 2 by decrementing the loop index by 2:
PERFORM procedure-1 «THROUGH procedure-2» «WITH» TEST AFTER UNTIL condition or PERFORM «WITH» TEST AFTER UNTIL condition expression END-PERFORM: PERFORM procedure-1 «THROUGH procedure-2» VARYING i FROM first BY increment UNTIL i > last or PERFORM VARYING i FROM first BY increment UNTIL i > last expression END-PERFORM — Rust: while ...
In computer science, a for-loop or for loop is a control flow statement for specifying iteration. Specifically, a for-loop functions by running a section of code repeatedly until a certain condition has been satisfied. For-loops have two parts: a header and a body. The header defines the iteration and the body is the code executed once per ...
The post-increment and post-decrement operators increase (or decrease) the value of their operand by 1, but the value of the expression is the operand's value prior to the increment (or decrement) operation. In languages where increment/decrement is not an expression (e.g., Go), only one version is needed (in the case of Go, post operators only).
In computer science, a generator is a routine that can be used to control the iteration behaviour of a loop.All generators are also iterators. [1] A generator is very similar to a function that returns an array, in that a generator has parameters, can be called, and generates a sequence of values.
In computer programming, foreach loop (or for-each loop) is a control flow statement for traversing items in a collection. foreach is usually used in place of a standard for loop statement.
do index = start [to limit] [by increment] [for count] [instructions] end. The increment value is 1 if the by clause is omitted. The loop continues forever if the limit to clause is omitted. The language permits counted loops, where an expression is computed at the start of the loop and the instructions within the loop are executed that many times:
For brevity, these words will have the specified meanings in the following tables (unless noted to be part of language syntax): funcN A function.
