Dog Faced God said:Standing up from prone precludes you from charging. If you charge (partial, full, hasted or otherwise), all movement in the round must be in a straight line. The act of standing is basically a 5' step in the UP direction that requires a move equivalent action.
Actually, it is not.
For example, you can get up, move 5', and still attack since as long as you move no actual (horizontal) distance with a move equivalent action portion of a standard action, you can still move 5 feet and do the "action portion" of the standard action.
Getting up is a move equivalent action, not a move.
