An IDI workstation (or device) name is simply a character string (for example,
xwindows) which identifies an image display and its type. The default
device name can be overridden by appending a semicolon followed by the new
device name after the workstation name.
Environment variables can be set up and
translation proceeds recursively until a name is found that does not
translate to another name.
