The first eight lines are input during initialization of the program.
All text after the first eight lines is ignored. The first eight lines
contain the mnemonics of the unimplemented op-codes and can be changed
by the user to work the problems from Chapter 8 of "Computer Systems".

Mnemonic, followed by whitespace, followed by allowed addressing modes in
any order, whitespace delimited. First four mnemonics are assumed to be
unary.
