In "Glossary of z/OS terms and abbreviations" (no title page nor part #;
apparently for z/OS 2.3) I see the (somewhat garbled):
megabyte (MB). 220 bytes, 1 048 576 bytes.,048,576 bytes.
??? (sic)
I find no similar entry, correct or incorrect, for "kilo*".
I wonder which convention IBM uses when it specifies the
shipping weight of a z in kilograms? If IBM can flout SI in
some cases, why not in all?
