last-in-chain (LIC)

The last segment of a message whose entire length exceeded 256 bytes, transmit- ted by an SNA (systems network architecture) application or by the protocol emulator (PE) to the SNA side of the network, in a session governed by profile 3 or 4 protocol set. That the element being transmitted is last-in-chain, is specified by a setting in the chaining control field of the request header. InEC (emulator control) and XEC (extended emulator control) modes, the PE sets the chain indicator in messages it is transmitting to SNA. For messages flowing the other way, SNA sets the chain indicator.; 在由第3或第4協議子集所控制的話路中,由SNA(系統網絡體系結構)應用程序或由協議仿 真程序(PE)發送到網絡SNA側的長度超過256個字節的報文的最后一段。正發送的這一元素 最后進入報文鏈,并通過在請求報頭的鏈控制字段中進行設置來規定。在EC(仿真控制)和 XEC(擴充仿真控制)中,PE對發送到SNA的報文設置鏈指示符。對于遵循另一種方法的報文, SNA設置鏈指示符。
