Parameter

command-string

   Specifies a command string of less than 132 characters that is
   to be executed in the context of the created subprocess. When
   the command completes execution, the subprocess terminates and
   control returns to the parent process. If both a command string
   and the /INPUT qualifier are specified, the specified command
   string executes before additional commands are obtained from the
   /INPUT qualifier.

   If the command string contains apostrophe substitution, the
   apostrophe substitution is performed in the context of the parent
   command line interpreter (CLI); other phases of substitution are
   performed in the context of the subprocess CLI.
