Increasing/Decreasing Stats By A Value, Not A Percent

[Cubefreak101]

I'm not sure if this should go in the scripting help, or here because I don't know if this could be done without scripting. As the title suggests, I want to increase Phys Defense, Magic Defense, Strength, etc. by a specific value as opposed to a percentage. I want to boost the actor's strength, for istance, by 5 points, instead of increasing it by 5%. How would I go about doing this, using a script or otherwise?

That can be done with the "Change Parameters" event command.  Alternatively, using a script:

   actor=$game_actors[1] # actor 1
   value=5
   # Adds 5 to all parameters
   actor.maxhp += value
        actor.maxsp += value
        actor.str += value
        actor.dex += value
        actor.agi += value
        actor.int += value

Actually, upon closer inspection, PDEF (physical defense) and MDEF (magical defense) both depend on the weapon and armor used, and states inflicted.  The same applies to ATK, HIT, and EVA.  These are not parameters, so they can't be set in the same way.  Strength (STR), however, is indeed a parameter, which can be set using the above code.
