ABAP中控制程序源码

如何将report程序的源码读入内表，并进行修改操作?ABAP中提供一系列指令来实现此功能。语法如下：

INSERT REPORT prog FROM itab.    根据内表内容更新程序

READ REPORT prog INTO itab.        将程序读入内表

DELETE REPORT prog.                           删除程序

 

示例程序：

DATA sourcecode(120) OCCURS 0 WITH HEADER LINE.
DATA length TYPE i.
READ REPORT 'ZTEST' INTO sourcecode.
DESCRIBE TABLE sourcecode LINES length.
length = length + 1.
INSERT '*Comment Line.' INTO sourcecode INDEX length.
INSERT REPORT 'ZTEST' FROM sourcecode.
