green bytes
(foldoc) | green bytes
green words
(Or "green words") Meta-information embedded in a
file, such as the length of the file or its name; as opposed
to keeping such information in a separate description file or
record.
By extension, the non-data bits in any self-describing format.
"A GIF file contains, among other things, green bytes
describing the packing method for the image".
At a meeting of the SHARE Systems Division, November 22, 1964,
in Washington, DC, George Mealy of IBM described the new
block tape format for FORTRAN in which unformatted binary
records had a Control Word. George used green chalk to
describe it. No one liked the contents of the Green Word (not
information, wrong location, etc.) so Conrad Weisert and
Channing Jackson made badges saying "Stamp out Green Words".
This was the first computer badge.
Compare out-of-band, zigamorph, fence.

(jargon) | green bytes
n.
(also green words)
1. Meta-information embedded in a file, such as the length of the file or
its name; as opposed to keeping such information in a separate description
file or record. The term comes from an IBM user's group meeting (ca. 1962)
at which these two approaches were being debated and the diagram of the
file on the blackboard had the green bytes drawn in green.
2. By extension, the non-data bits in any self-describing format. “A GIF
file contains, among other things, green bytes describing the packing
method for the image.” Compare out-of-band, zigamorph, fence (sense
1).
