I remember answering this same question for you back in August here. I take it you didn't understand the resources back then, or did you read them at all?

It's pretty straightforward. Whenever HP changes (you should know when this happens), update the life bar (you should know how to do this).

solved();

There are a few ways to do this. What will you be using as the graphic for the health bar? An icon with a bunch of icon states? Or a rectangle for current health over another rectangle for maximum health? Or something else?

Either way, the question you asked requires some assumptions; that you have a property "health" that causes something to happen when it changes.
mob/whatever
    var health, max_health

    proc
        // You should use this wherever you want to change health.
        // You shouldn't set health directly anywhere else,
        // unless you don't want the health bar to update.
        // You should never be writing:
        //   health = x, or
        //   health += x, or
        //   health -= x
        // in any other proc.
        SetHealth(Health)
            // Set the health variable to the new value.
            health = Health

            // Call side-effect(s) of changing the health variable.
            UpdateHealthBar()

        UpdateHealthBar()
            // update the health bar.
            // What gets written here depends entirely on what YOU want it to do.
            // (this goes for literally everything else in your game, too)
