Switch Loop with Boolean expressions? Can it be done?

So I am trying to get a switch loop to display values of x=rand(1,10) when the values are greater than and smaller than 0.6?
Been trying with this however it keeps either telling me that my x value needs to be a scalar or character variable or just the regular unexpected error message.
switch (x)=true
case (x>0.6)
disp 'Large value in x found'
otherwise (x<0.6)
disp 'Small value in x found'
end
I know something else would be probably more pragmatic here but it's homwork so I do not make the rules...
Thanks in advance!

switch true
with no variable..
Also the otherwise should not have a condition

As Walter said, yes you can do this.
As Walter also recommended, you shouldn't do it. The majority of readers (particularly people familiar with C-like languages) would expect a constant in the case expression and a non-constant expression for the switch. You're going to confuse a lot of people if you use that syntax.
If you do use it despite our recommendation, then a comment in the code explaining in details why it is used (as opposed to the simpler and clearer if...else) would be extremely recommended.
