the printer message queue. It is placed in the printer message queue

after the user presses <ENTER>.

3. Incomplete messages are not available to QREAD().

4. Each message pointer can be moved with QSKIP().

5. If the OS Console is an RS232 or Telnet connection, and was

defined with the no_printer flag, this command will not work with

that OS. See QOPEN() for more details.

Example:

//==============================================

// Example 1

//==============================================

%Wait := 180

%QID := QOPEN() //open queue on current OS

WHILE TRUE //repeat process continually

$Msg := QREAD( %QID, $MsgArray, %Wait)

IF $Msg == “” //if null, then no msg was

received

//the building of the $Temp string to display

//on the log is done this way here simply due to

//width restrictions of the printed page

//Normally, build it on one line or place the

//entire string in the LOG command

$Temp := “No messages in ” + STR( %Wait)

$Temp := $Temp + “ seconds on OS: ”

$Temp := $Temp + $MsgArray[ 1])

LOG( LOG_FLT, $Temp, STATUS_WARNING)

ENDIF

//check first word of msg for IO

// err $MsgArray[ 1] will always

//have OS name

IF $MsgArray[ 2] == “IOS000I”

//call IO err handling script passing OS name

IOERROR( $MsgArray[ 1])

ENDIF

ENDWHILE

//====================================================

// Example 2

//====================================================

%Wait := 30

%ObjIDSys5[ 1] := OBJID( OS, “SYS5”)

%QIDSys5 := QOPEN( %ObjIDSys5)

$Msg := QREAD( %QIDSys5, $MsgArray, %Wait, “error”)

IF $Msg == “” //if null, then no msg was received

$Temp := “No msgs for ” + STR( %Wait)

$Temp := $Temp + “ seconds: ” + $MsgArray[ 1]

LOG( LOG_FLT, $Temp, STATUS_WARNING)

ELSE

LOG( LOG_FLT, $Msg, STATUS_ERROR)

ENDIF
