Use the CLASS command to indicate an
"output class" or a "processing class"
for the file being sent.
The CLASS statement
must come after a FILE command and should
preceed any DATA commands.
The syntax is
CLASS | class code |
where
class code | is typically a single letter |
The class code will almost certainly have
local dependencies and/or restrictions.
This attribute is
generally most useful for print jobs, though it can be used
to specify other media types and may be applied to non-printed files.
An augmented syntax is
CLASS | class code [ devtype ] |
where
class code | is typically a single letter |
devtype | is a device type somehow related to the class |
