1. What is the primary purpose of the 'DO WHILE' loop in REXX? A. To execute a block of code a fixed number of times B. To iterate over a collection C. To repeat a block of code while a condition is true D. To define a function Show Answer 2. What keyword is used ...
所以Do...Loop系列语句实际中可以有两个条件分别判定是否结束循环。...do while...loop循环语句 do while...loop语句属于先测试循环条件的语句,首先来看下它的语法结构。...(注意是在循环结构之前先赋值。) 2、do while 循环 代码中的主要部分就是do while循环,while循环的条件是i<10。
起初Fortran语言,年代:1954年,作者:约翰·华纳·巴克斯,绝大多数是IBM公司。 IBM公司语言:Fortran、PL/I、Rexx。 do和for很类似,也有do循环联合(do-while) loop循环 loop起初是个联合,起初CPL语言,年代:1963年;loop-to起初的是NetRexx,年代:1996年。 loop联合:CPL、SETL。 loop独立:Arturo、Clojure、Ada、Rust。
问执行do时间和退出EN将所有代码包装在一个循环中，并使用一个布尔变量(如keepRunning)，该变量被初始化...
End k /* Checks that this is the END for K loop */ Note:The NUMERIC settings can affect the successive values of the control variable, because REXX arithmetic rules apply to the computation of stepping the control variable. Conditional phrases (WHILE and UNTIL) ...
See Conditional phrases (WHILE and UNTIL). Simple repetitive loops A simple repetitive loop is a repetitive DO loop in which the repetitor phrase is an expression that evaluates to a count of the iterations. If repetitor is omitted but there is a conditional or if the repetitor is FOREVER, ...

Conditional phrases (WHILE and UNTIL) A conditional phrase can modify the iteration of a repetitive DO loop. It may cause the...
