Hi, 
I am missing a few features. Do any of the following exist and I have just
overlooked them?

- Arithmetics:
    SET foo, 2
    SET bar, 2
    SET FOOBAR, $foo + $bar
    -> FOOBAR is 2, not 4

- Vectors/arrays
    As far as I understand, "SET" only allows for single variables and no 
    "scripting" in variable names, i. e. doing something like the following
    scripted: 
    SET var_1, 0
    SET var_2, 0
    ...
    LOOP n, 10
        ...
        IF something
            SET var_${n}, 1
        ENDIF 
    
    The only way I could think of doing something similar is via the ODB.
    I don't know if it's good practice to fill the ODB with variables like this.

- Loading scripts at run time (see other bug)
    That would allow for script manipulation, even though it's kind of dirty, it
    might be useful in some cases.

- Obtaining results from external scripts
    A way to pass things from external scripts would be the solution to all
    problems. Something that is not implemented could be done in a bash or
    python script instead. 

Cheers
Lukas
