刚看了下帮助 _status_这个系统变量值通常为: (我E文差就不翻译了,其实看字面意思也容易懂的~ <!-- s:) --><img src="{SMILIES_PATH}/icon_smile.gif" alt=":)" title="Smile" /><!-- s:) --> )
' ' (blank) A control or field was modified or selected.
E An END or equivalent command was issued.
C A CANCEL or equivalent command was issued.
P A pop-up menu event occurred.
G The getrow section was called for the top row of an extended table.
K A command other than an END or CANCEL, or their equivalents, was issued. Valid only for FRAME entries.
D A control was selected with a double click. Valid only for FRAME entries.
如果要给_status_赋值的话只有2个值 R 和 H
H 就等于是发送END命令
R 是取消END或CANCEL命令 只能用在term段中
