For one thing, INDIGO ISN'T A REAL GAME! but usually, you go to the Pokemon section of your game by pressing X or Start, then select the Pokemon you wish to switch, then scroll to Switch, then it will have you click the place you want to switch. There you have it! But, for the record. Whoever sold you Pokemon Indigo, sold you a fake game.

Well, it depends what you mean. If you mean switching Pokemon to change the order in which they come out, you have to select the Pokemon and click on switch. Then choose what Pokemon you want to switch it with. If you want to take Pokemon from your PC and put in your main party, then go to any Pokemon center, go to the blue computer to the right of the nurse and press A. Select the first option, and select DEPOSIT POKEMON. Then choose the Pokemon in your party in which you want to remove and select DEPOSIT. Then press B and reply no to the question. Then select WITHDRAW POKEMON. Then select the Pokemon in the box that it is in and select WITHDRAW
the same place you bought them
