As far as I know all COBOL compilers do not align data unless it is
specified. I think that this may be specified in the standard. Usually
data in COBOL is decimal, but can be binary. Not that this really matters.

[My recollection, since it's been a while since I wrote any Cobol, is that
Cobol lets you overlay picture data, which is characters. You can tell it
to store it in binary (COMPUTATIONAL) but I believe that compilers can
weasel around and stick the binary version somewhere else. -John]
