这是我的代码，我刚刚开始abap编程，想做一个小程序来学习...但是我被困在从本地计算机上读取txt文件，我无法继续...错误说文件没有打开...和cx_sy_file_open_mode捕获的异常
data file(100) value '.\myfile'.
data num type string.
open dataset file for output in text mode encoding default.
close dataset file.
然后将read_data更改为：
class-data: num type string.
查找并将所有read_data更改为num。
