Switch case simple mistake

Hi, why doesnt 'works' show when i run this? Is it because the case has to be the switch input?

 inStr='d'
 switch inStr
    case inStr(1)=='d'
    outStr='works'
 otherwise
    'error'
end

case inStr(1)=='d' evaluates inStr(1)=='d', generating the value false or true. That value is then compared to inStr because of switch inStr, and is found to not equal to inStr.

switch inStr(1)
  case 'd'
