ADDRESS REXXCICS 'DIR'
ADDRESS is a keyword instruction.
When you specify an environment and a command on an ADDRESS instruction,
a single command is sent to the environment you specify. In this case,
the environment is REXXCICS. The command is the expression
that follows the environment: 'DIR'
The DIR command lists the files in your current
file system directory. For more details about changing the host command environment, see
section Changing the Host Command Environment.More information about issuing commands appears in Using Commands from a program.
