问题 I've been searching for some time now, and I'm sure I've missed it, is there any documentation that states what should be thrown when a value is incorrect/blank? For example, Python has ValueError and the documentation clearly states when to use it. I have the following method: proc getJobinfo {question} { puts -nonewline "$question: " flush stdout gets stdin answer set cleanedanswer [string trim [string totitle $answer]] if {$cleanedanswer eq ""} { # What error should be thrown? } return
