There are two basic command environments: the control program (CP) command environment and the virtual machine command environment. You are in the control program (CP) command environment when you log
on to VM/370 and issue CP commands. You are in the virtual machine command environment when you load your
virtual ffiichine CMS or another operatinq system.
If YOl are operating under CMS, you can determine which command
environment you are in by enterinq a null line (that is, pressing the
enter key, oc equivalent, with no data). VM/370 responds to a null line
by displavinq the current command environment, CMS or CP. VM/370 CP Command Structure A VM/370 =ommand consists of a command name, usually followed by one or
more positional operands. The general form for the CP command line is: r 1 command. name
