Eval '-' operator does not work with strings in variables - NinjaKyat - 08-15-2017
Hi!
First thing's first - currently if you try and eval with a string, number and the minus '-' operator, it trims a number of characters from the end of the string.
So, if you do something like "eval pootis 1 -" it outputs "poot". (Not sure why 0 trims 1 character, 1 trims 2 characters, but I guess it doesn't really matter. Just a bit confusing).
However, if you have a string stored in some variable, like var and you try doing "eval var 1 -" you get nothing. No output. Trying to store the result in a variable also does nothing.
The '+' operator works and it concatenates the string, so I assume there's some sort of bug in here or my misunderstanding in the inner-workings of the system.
