单元命名规则
对于复杂的程序，可以将其编写为多个INCLUDE，不同作用的代码放在不同的INCLUDE中，各个INCLUDE的名称按下表编写
 
代码的作用 单元名称   
Events（TOP－OF－PAGE等） ZXXXXE01   
Subroutines（Form routines） ZXXXXF01   
PAI Modules ZXXXXI01   
PBO Modules ZXXXXO01   
Global Data ZXXXXTOP   
Input Help ZXXXXH01 
其中：ZXXXX为程序名。

事件代码必须遵循编写顺序
Initialization

At Selection-Screen OutPut

At Selection-Screen

START-OF-Selection

At Select-Screen on XXXX

At Select-Screen on value request for XXXXX

At Select-Screen on help request for XXXXX
