Thanks, so the eval steps easily creates a dynamically named variable.

The idea is to proceed to use the newly named variable and its value in 
another function, passed on in parameters, something like:
nextFunction('variable_name','the_value')

nextFunction(name,value){
alert(name+'='+value)
}

As the combined variable name became 'zebrastripes' and its value being 
whatever the document title is, the function may then return a string like:

zebrastripes=some document title

How can the dynamically created variable name and its value be passed as 
two strings onto the nextFunction()? Or even set as a global variable/value 
pair which can be accessed in another function?

Many thanks for any additional tips.
