hi!
i dont know, how the syntax for a switch-case loop, works.
i tried something like:
x = 1
switch(x)
case 1: return “bla bla”
case 2: return “hoho”
end
but nothing. im sure is very easy, but i have no idea how the syntax is.
can anyone help? ty!!
Wrong words, though it’s quite easy to go look this kind of stuff up in
any
Ruby documentation (Pragmatic Ruby Guid comes to mind).
Here’s the syntax:
case expr
[when expr [, expr]…[then]
expr…]…
[else
expr…]
end
Jason
try
case x
when 1:
when 2:
else
end
it, er, is in the manual…
allbests,
…

You want:
case x
when 1
return “bla bla”
when 2
return “hoho”
end
