Fsearch,if Else problems

I know I shouldn't, .....

  I just couldn't help my self....
  Don't do what I do, do what they say ! 

One could also create a haslist for all commands allowed, then do a binary search in the hashlist?

Or use nested case statements.
Say we have 3 commands: Help, Halt, Install:

Code: [Select]

case Command[1] of
  'H': case Command[2] of
         'E': case Command[3] of  etc. etc.
         'A':
         else //code for wrong input here
        end; 
  'I':  case Command[2] of
         'N': case Command[3] of etc.etc.
         else //code for wrong input here
       end;
  else //code for wrong input here
end;

(I actually once wrote such piece of code with nested case statements to decode codons (3 successive letters (array[1..3] of char), coding for an amino-acid), where this approach proved to be faster then any other alternative anyone else came up with.)

Abstract a little futher and you end up with a design pattern
