In a MPF exit, you can set any message you are processing to any color (of the 8 available) and any highlight, reverse video, blinking mode you want (and which is supported by the terminal it's going to be displayed on), and you can additionally take actions on what the message said, and decide even to not display the message at all (after all you just "fixed" whatever it was the message represented). There is very little that you can NOT do with an MPF exit. The only restrictions are WAIT related types of things, and even that isn't really a restriction, just a really, really good idea not to wait.
Of course, our SyzMPF/z product does all of this for you and lets you make the decision based on any number of variables, but it's not free like the MPF exits on the CBTtape or some of the web sites others have mentioned. The advantage is that SyzMPF/z can do hundreds of things besides just changing the message display values and it's a supported product which is upgraded (some might say too) frequently. Unfortunately, it's not free. That said, there are some pretty good MPF exits that you can run for free, they don't do as much and can't perform some of the really cool things that SyzMPF/z can do, but they are free. If they do what you want, and you are okay with supporting it yourself, then it would be silly to pay someone else for that.
