Switch goes very well with enums - that is true but if the memory gets corrupted and you have some garbage there? Dorin, in that case you need to check the variable after you finish with the switch.

For example, if you do a color = 0x0; switch (colid) { case WHITE: color = 0xFFFFFF; case BLUE: color = 0xFF0000; etc. } Nobody will punish you. Rule of thumb: switch goes very well with enums. :) And the compiler will notify you that you forgot a case or more (gcc does, at least, and any decent compiler should).
