前言

用户想在ALV上编辑长文本，但是ALV只有128个字符肯定是不够用的，所以需要用一个长文本编辑器来输入，本来想自己写的，发现有标准的函数，还挺好用的

代码

在用户双击ALV字段时，触发下述form，分别以修改/显示模式弹窗长文本编辑器

*&---------------------------------------------------------------------*
*& Form frm_click_stkt1
*&---------------------------------------------------------------------*
*& text
*&---------------------------------------------------------------------*
*&      --> PV_SELFIELD_TABINDEX
*&---------------------------------------------------------------------*

挺好用的，不错不错
