specifies one or more
valid system commands. The string can contain upper- or lowercase
characters. Separate multiple commands with a command delimiter,
which is host-specific; for example, some operating environments use
a semicolon. The total length of the string cannot exceed 72 characters.
The commands are executed right after the graph is produced.

If you want to use a
host command to send output to the device after each graph executes,
use the POSTGRAPH parameter with FILECLOSE=GRAPHEND.
