I suppose that Philips CGI solution is what you are really after. 
However, if you still want to create variables as in your example, here is
how:

Use the 'eval' function.  A first thought is to type:

eval "#{key} = #{val}"

But this has the problem of scope.  This is read as:
eval "anfang = '123'"

'anfang' is local to the eval, and it disappears when the eval is done. 
The best you can do is to make it a global variable:

eval "$#{key} = #{val}"

Now $anfang exists after the eval is done, and it has the value '123'.

I hope you realize that, as it is, '123' is a string, not an integer. 
Perhaps what you want is:

eval "$#{key} #{val.to_i}"

Cheers,
Daniel.
