This tutorial is kind of a response to the on in:
http://www.compsci.ca/v2/viewtopic.php?t=3270
Getch
Getch is the command for "get char"...which waits until the user inputs(presses) a button (character) on the keyboard, then it saves it under a variable name. This can be used for buttons too, like (KEY_UP_ARROW), etc.
Input.KeyDown
This does similarly the same thing...except it can handle multiple characters (enabling 2+ player programs). These extra characters are held in a boolean array, thats why the variable is declared like so:
code:

var chars:array char of boolean

Mousewhere
The mouse is an uncommonly used tool for movement. There are easy ways this is done though, like 4 if statements, checking the mouses x and y co-ordinates relative to the players. Then if the player clicks, and (for example) the x and y are greater than the sprites x and y, the sprites x and y increase as a movement step.

I have included a program showing you how each of these movement types work.
