Basically if %1 is empty, this will end up being IF . == . and so the GOTO will happen. We use x here so: IF x%1 == x -> IF x==x -> true

You should aks for what is the value of a "unprovided argument"? Againts what you should check an "unprovided argument"? Then, if you don't have an answer, you should use a trick like the one of the dots. Remember that, like stated here ss64.com/nt/if.html "You can in fact use almost any character for this a '~' or curly brackets, { } or even the number 4, but square brackets tend to be chosen because they don't have any special meaning."
