- The function codes PICK and PF## ("##" stands for 01 to 24) do not cause the event AT USER-COMMAND, but the events AT LINE-SELECTION and AT PF##.
功能码PICK和PF##(‘##’代码01到24)触发事件AT USER-COMMAND，但是能触发AT LINE-SELECTION 和 AT PF##。
- All function codes that start with the character "%" are interpreted as system functions and do not cause the event AT USER-COMMAND. The system functions for lists are listed in the following table 1.
所有的以字符%开始的功能码被看作是系统函数并且不会触发AT USER-COMMAND事件。系统函数列表被表在如下的表1中。
