Can you identify this TV show?

I remember an animated TV show where the characters lived inside of a computer. It was very cleverly done - the characters' names were computer terms: a boy named "Bob', a girl named 'Dot', a dog called 'Frisket', and even a villainess called 'Hexadecimal.' They would hear a voice saying, 'incoming game', and if they were caught in the game cube, they would have to play the game and win to survive. Does anyone remember the show and the title?
