First of all - i guess your asking the question of - how can i do a command to get me past level 40/50 as this is the max you can enter. Now i have not bothered looking because for a normal player - they level as per normal and as a GM - you can level up 50 or higher if you do a Minus number (say -7 for example).
So what are you trying to achieve??? Let me explain the hex's above - after a certain level (46 i think) the Exp required is uber high - so would take a normal player a long time to get to next level - what you do is as above and then there is extra level (52 i think it said) above from the normal. This puts in the EXE values which its shoves into the database for that person to get from one level to the next.
If you played as a normal player then you can carry on going up the numbers as long as you get the Exp - what made you think there was a limit of level 40?
