[Mean]

Example of reading:

pawn Code:

forward LoadMyStats( playerid, name[ ], value[ ] );
public LoadMyStats( playerid, name[ ], value[ ] )
{
    if( !strcmp( name, "Score", false ) )
        SetPlayerScore( playerid, strval( value ) );
    return true;
}

To load the score from file:

pawn Code:

INI_ParseFile( account, "LoadMyStats", false, true, playerid, true, false );

Simplest way I can think of.
