Subject: Re: Dynamic Variable Names

Hi Chris,

I'm not positive I understand precisely what you want, but if you want 
to store/access a variable via a String values, you can do this via 
"Module::eval" or other similar techniques:

def test
   static = "static"
   dyno = "_dynamic1"
   data = "store me"
   eval(static+dyno+"='"+data+"'")
   # call it via hard code
   #call it dynamically
   eval("puts "+static+dyno)
end

test

I think this gets you where you want to be. For some reason, calling 
"static_dynamic1" hard coded wasn't working for me but if you need to 
go both ways, I'm sure it's possible. Not also the weird use of quote 
marks in the eval code. You have to quote "one layer" deeper than the 
code - but that's probably the same PHP

Best,

Steve
