It also seems you don't understand how the -z switch works
I sort of know how the -z switch works I read the help file lol, was just one idea to set jail to 0 but the -z switch unsets it so wasn't sure if you still needed it to be set or not, the above example was just answering Purcell's question.
Otherwise I would have done it like this, which would decrease and unset in 1 second:

var %temp 1
hadd -z $2 jail %temp

Instead of

hadd $2 jail 0 

Purcell: I looked at the hash table help file for the first time ever today, so no I cannot help you as I am not skeeled enough, please Read the help file dude and please don't flood, if you have something to say and think of something later on to say, click EDIT and add what you wanted to say with your previous post.
