    [ovedpo15]: how fast and a good way to print error if more than one out of three variables are defined? for example if there are $a $b $c. I want that if for example $a and $b are defined - print error (also for $a and $c or $b and $c)
    [ovedpo15]: its easy with three "if"s or one long "if" but is there a "nice" way :)
