Thanks for the style pointers. I'm a scientist, not a programmer, so it will be rough going while I learn.
What I wanted was an exception (try/except) in case any of the reads failed. Corrupt files are an expected case that should be handled by the program. So I can't crash while reading (or writing). Does Squeak have exceptions? Or is there a Smalltalk pattern for this "try to execute this, do something else if it fails"? That answer should probably go into another thread.
