而ABAP中传递的是否为地址,则要看实参是否是通过Type ref to定义的)传递;但如果USING值传递,则对形参数的修改不会改变实参,因为此时不是引用传递;但如果CHANGE值传递,对形参数的修改还是会改变实参,只是修改的时机在Form执行或Function执行完后,才去修改 Form中通过引用传递时,USING与CHAN
[SAPABAP开发技术总结]Form（subroutine）、Function参数 传值传址 这节也是ABAP学习的关键所在，Form、Function、Method的参数定义都差不多，弄懂⼀个，其他都好办。参数传递涉及传值、传址问题，这是其也语⾔也有的问题，要学好他，你得要仔细想想 1.10. Form 、 Function 、 Function 中的 TABLES 参数， ...
传统系统开发:在SAP ECC等系统中,ABAP子程序曾是模块化开发的核心手段,通过FORM...ENDFORM语法定义业务逻辑。 三、语言特性与扩展形式 词性变化:复数形式为subroutines,表示多个子程序集合; 自动执行机制:augomatic built-in subroutine由系统触发,如异常处理回调函数; 多语言支持:不同编程语言中...

If used wrongly, dynamic programming techniques can present a serious security risk. Any dynamic content that is passed to a program from the outside must be checked thoroughly or escaped before being used in dynamic statements. This can be done using the system classCL_ABAP_DYN_PRGor the pre...
