Option (1) -- This option determines whether PRETTY defaults to quiet mode. 
Whatever is chosen here can be toggled with a "Q" option on the command 
line.

Option (2) -- PRETTY tries to determine itself whether the source file 
contains Intel or Zilog opcodes.  If it can't figure it out, it defaults to 
the mode selected here.

Option (3) -- Opcodes and common pseudo-ops will be made lower-case or 
upper-case, depending on your selection for this option.

Option (4) -- Labels and any operands not recognized by PRETTY will be 
converted to the case selected here.  You can also select "AS IS" and the 
case of labels and less common opcodes will not be changed.
