Alternate for Case Code

     Is it possible to replace the code between the braces with different code that is not a case statement.  I mean engineer a different way to do the same thing.  Possibly with a series of if statements or something such as "if B or b then x,  if V or v then y,  If Q or q then z."  If so what would the syntax be?  What code could replace this and plug into the same spot.  
{
                case 'B':
                case 'b':
                    filer.buildAFile();
                    break;
                case 'V':
                case 'v':
                    filer.viewAFile();
                    break;
                case 'Q':
                case 'q':
                    done = true;
                    break;
                default:
                    System.out.println("That is not a valid choice.");
                    break;
            }

you did not specify the switch !!!!

I assume switch (a)

if ( a == 'B' || a == 'b' )
    filer.buildAFile();
else
    if ( a == 'V' || a == 'v' )
           filer.viewAFile();
    else
        if ( a == 'Q' || a == 'q' )
           done = true;
        else
            System.out.println("That is not a valid choice.");

this should give you an idea though sytax is Cish

Cheers!

the syntax you used is java like syntax,

the vb syntax should be

select case Lcase(switchtext)
   case "b":
      filer.buildAFile();
   case "v":
      filer.viewAFile();
   case "q"
   else
      System.out.println("That is not a valid choice.");
end select

or...

if using C/C++
a = toupper(a);
Java String
a.toUpperCase()

if ( a == 'B')
    filer.buildAFile();
else
    if ( a == 'V')
           filer.viewAFile();
    else
        if ( a == 'Q')
           done = true;
        else
            // whatever your message

My question is:  Could I do what the Case statement does a different way.. maybe using a series of  "if" statements.  Can I cut out this case statement and replace it with a series of if statements?  What would this look like?
