If you'll try it this way in the end you'll find Smalltalk is an
awkward language for that kind of program.
You need to think about Bridge in Bridge terms and then this will
translate nicely into Smalltalk objects and methods.
I suggest you Google for Squeak by example (free Book) so you get a
feel for Smalltalk
Sorry I know noting about Bridge but when you can show most parts of
that Smalltalk program to a bridge player and he will have no problem
following what the program does then you wrote a good Smalltalk
program. Bits in Arrays of Bytes don't fall into this category.
Hope someone who knows about Bridge chimes in.
