Indicates whether any outstanding host remote console messages are waiting to be received.

Syntax

                     D       IA     
NRJEConsCheck ( ConsoleId, Result )

Parameters

ConsoleId

An input double-word integer variable. The ConsoleId parameter is the remote host console identification. Obtain the value for this parameter by calling NRJEConsole before you call this intrinsic.

Result

An eight-element integer output array. The Reply array contains error codes which occurred during execution of this intrinsic.

If no error took place, and a message is waiting, the first element of the Reply array is set to zero. If the first element of Reply=97, no message was received.

The structure of the Reply array is the same as the Result array described in "Parameters Common to NRJE Intrinsics," in the introduction to Chapter 5 “User Intrinsics”

Always test the first word of Reply to determine whether any outstanding host remote console messages are waiting to be received. The first word of Reply is set to zero if no error took place.

Description

Call NRJEConsCheck to indicate whether any outstanding host remote console messages are waiting to be received. Obtain the ConsoleId value by calling NRJEConsole first. Test Reply to determine if messages are waiting to be received.

NOTE: The NRJEConsCheck intrinsic uses Reply as a message-waiting indicator. Other NRJE intrinsics use the last formal parameter for error indication only.

While you own the host remote console, you receive all recent host remote console messages directed to your workstation. These messages may be in response to commands other than those you issued.

NRJEConsCheck is used with the following intrinsics:

  • NRJERcvMsg: to read one recent remote host console message.

  • NRJERelease: to relinquish ownership of the remote host console.

Text Reference

See the SNA NRJE Node Manager's Guide for the description of "Host Console Commands."
