I need to read very large files so a single ByteArray holding all the
data wouldn't work (not until I get a 64-bit version of Squeak).
However, I could read in one or more structure at-a-time as a
ByteArray and then parse out the data I need, then read the next
sequence. This is kind-of like a buff
Yes, if you can load the contents on a ByteArray you can use the method:
array floatAt: position
It works just fine to read contents written from a C program, and I think it
is a bit simpler.
Cheers.

Thanks. The following methods work, can they be improved/simplified?
double
" returns a double "
| n a b |
a := self uint32.
b := self uint32.
n := Float new: 2.
n at: 1 put: b.
n at: 2 put: a.
^n

An instrument I am working with creates a complicated binary file
(memory dumps of C structs). I would like to try reading the file into
Squeak for a cool new project. What's the best way to set up and read
C-based structs and then, once I'm done, to write them back out again
