+@end table
+
+@item int32 width
+The width of the display column for the variable in characters.
+

+The @var{value} field is exactly 5 bytes long. It is a zero-padded,
+ASCII-encoded string that is the length of the variable.
+The @var{key} and @var{value} fields are separated by a @samp{=} byte.
+Tuples are delimited by a two-byte sequence @{00, 09@}.
+After the last tuple, there may be a single byte 00, or @{00, 09@}.
