# REPEAT 程序 附件 prog.txt 中是一个用某种语言写的程序。附件在本文的末尾。 其中 REPEAT k 表示一个次数为 k 的循环。循环控制的范围由缩进表达，从次行开始连续的缩进比该行多的（前面的空白更长的）为循环包含的内容。 ![](https://img-blog.csdnimg.cn/20210320200704647.png?x-oss-process=image/watermark,type_ZmFuZ3poZW5naGVpdGk,shadow_10,text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM0MDEzMjQ3,size_16,color_FFFFFF,t_70) 该片段中从 A = A + 4 所在的行到 A = A + 8 所在的行都在第一行的循环两次中。 REPEAT 6: 所在的行到 A = A + 7 所在的行都在 REPEAT 5: 循环中。 A = A + 5 实际总共的循环次数是 2 × 5 × 6 = 60 次。 请问该程序执行完毕之后，A 的值是多少？ 题目给出的 prog.txt 文件： ``` A = 0 REPEAT 2: A =
