Whenever a card would go to a player's hand (they drew it, it got bounced, etc.) that player can put the card anywhere in their program they wish. At the beginning of each end step, if you have fewer than five cards in your program, you draw cards until you have five.

When The Grand Calcutron enters the battlefield, all players take their hands and place them face up on the table. They then order them as they choose into a row, called a "program." The only card they may cast is the first card in their program.

After The Grand Calcutron leaves the battlefield, players pick their cards up and put them back in their hand. They are no longer public and no longer follow the rules of The Grand Calcutron.
