Assistance with AutoDef and saving variables

[xBlueEyesx]

What I am trying to accomplish is having an autodef where I can do "deffup" and I will run through all the defences I am able to put up. Then I can do "deff" and I will only put up one defence that I am missing or has been stripped. I have no idea where to even start doing this so any help would be awesome and sample scripts would help alot.

Another thing how would I save variables to carry over to the next time I open mudlet such as maxhealth or anything like that.
