Hi All

I tried to print an "M" or "V" depending on the value of a variable,
like

@var = "v"
@var == "v" ? { p "V" } : { p "M" }

this however doesn't work, but I'm sure something like this can be done!
Any suggestions ?

Cheers
LuCa

And put brackets around the arguments of p, otherwise you'll get a syntax
error

In this case, I'd use a standard if:

if @var == "v"
p "V"
do_something
else
do_something_else
end
