REPEAT 语句定义了一个语句集合,如果在 REPEAT 循环结束时某个条件的求值结果为 true,那么就将执行这个语句集合。
The REPEAT statement defines a set of statements to be executed until a condition that is evaluated at the end of the REPEAT loop is true.
如果有一个为真了,相应的分支语句就运行了,这些条件判断的语句就都结束了。
If one of them is true, the corresponding branch runs and the statement ends.
