Erase／Write
擦去／写入(命令);［抹除／写入(命令)］
A 3270 data stream command that clears the entire character buffer to nulls, positions the cursor to position 0, resets the buffer address to 0, sets character attributes to their default values, and then performs a write operation. It also returns screen size to the default size if the WCC reset bit is set to 1.
IBM的信息显示系统3270中处理数据流的一种命令,有以下功能:把整个字符缓冲区清除为 空,置光标于位置零,使缓冲区的地址复位到零,把字符属性置为系统设定值,并实现写操作。 如果写控制字符(WCC)的重置位为1,则该命令还将屏幕的尺寸恢复成系统设定的尺寸。 |
