code !!Q is the interrupt code, a hexadecimal number to be associated
with the external interrupt. All codes within the range X'01' thLoucrh X'FF' are valid. If your virtual machine has the ECMODE option specified in the VK/370 directory, you can also code X'1004' (clock comparator interrupt) or X'1005' (CPU timer interrupt). The default is the external interrupt
button on the system console, X'40'. simulates pressing the interrupt key on the real computer console, or other functions which cause an external interrupt. Control is given
to the machine immediately.
None. Since control is given to the virtual machine, any response is
from virtual machine processing.

machine in the current terminal session.
1. Use INDI:ATE LOAD to display system load conditions.
2. Use INDICATE USER to display the total amount of certain resources
used by your virtual machine durinq the current terminal session. Use the INDICATE USER command before and after the execution of a pLogLam to indicate the execution characteristics of that program
