SMSG nse the command to send a special message to a virtual machine proqrammed to accept and process the message. The format of the SKS3 command is:
r----------T ---, , S Msq I userid msgtext , L __________ .L ___ J user id is the receiving aserid as "*", yourself. virtual machine's logon ID; if you specify
it indicates the message is to be sent to
msqt ext is the text of the message that is to be transmitted. Because
the input baffers on various console devices differ, the
length of the message is limited by the number of characters
remaining on the input line after entering the command and the aserid. For example: A 3270 display device contains a 139
character input buffer. If you enter:
1 • smsg pd58gh1c --------- 14 characters used
sm u '-v--' 5 characters used
special message ------------- 125 characters left
special message ---------- 134 characters left NQtg: the 3270 display unit contains 139 characters
in its input area, CP only reads 134 characters of data. When the SMSG command is issued using DIAGNOSE X'08', only 132
characters are read by CP. Special messages do not appear on the specially programmed
machine's· screen because the messages are designed instcactions that are passed as data parameters. The messaqes are stored in the prespecified VMCF data receiving

Virtlal machines can only receive and process special messages ander these two conditions: (1) the virtual machine has issued the SET SMSG command, and (2) the user wishing to receive special messaqes has issued an AUTHORIZE with the Virtual Kachine Cornm'lnication Facility (VMCF) of VM/370.

SPOOL Use the SPOOL command to modify the spooling control options in effect
for a given virtual spooling device or for a group of devices. The SPOOL command can also start or stop the spooling of virtual console
input and output. You can direct a file to a remote location by using
the SPOOL command in conjunction with the TAG command. This latter
function is discussed below in the section "Transmitting Files to Remote
Locations." The default values for this command appear under "Usage Notes" following the operand descriptions. The format of the SPOOL command is: SPool {

more than one may be specified, and they may be entered in any order

Furthermore, these options only apply to a 3800 printer as a virtual
spooling device. 13You can specify NULL for the name field to nullify any previous or I existing settings of the MODIFY, CHARS, or FCB operands. NULL 1 is the default. L--- Section 5. Format of CP Commands 141
