A '''flag''', also referred to as a switch, is any value for an address or multiple addresses which has an associated meaning such that it will trigger
In the Pokémon games, flags often exist in addresses as simple one-bit (2^1) integers. For example, in [[bp:Pokémon Diamond and Pearl|Pokémon Diamond and Pearl]], in the downstairs area of a Pokémon Center a value of 0 in a single byte denotes that the player has not received the Pal Pad yet, whilst a value of 1 denotes that the player has, so after the flag is checked to a value of 1 the associated event with a value of 0 (i.e. the assistant walking out and giving the player a Pal Pad) will not occur. Oversights by the game developers regarding an event which has not a flag required to start another intended event are often one of the main causes of glitches, for example the [[Tower Tycoon event skip]] glitch in Pokémon Diamond and Pearl is caused by choosing the 21st Battle Tower match by choosing to rest and then selecting the option 'NO', which would start a battle without setting the flag making another trainer appear instead of the [[bp:Tower Tycoon|Tower Tycoon]].
