Is there a way to create a Variable with the name of a String?
I would like to do something like this:
name = "VariableName" % String containing the name I want to give it
Variable(name) = 35
And then have a Variable called Variable Name, that contains data

That is not a good idea, explained in length (,depth and breadth) here - TUTORIAL: Why Variables Should Not Be Named Dynamically (eval)
Why do you want to do that?

"Is there a way to create a Variable with the name of a String?"
Yes, if you really want to force yourself into writing slow, complex, inefficient, obfuscated code that is fragile and hard to debug:
However in almost all threads on this forum (and others) related to this topic, creating such variable names dynamically was not a good approach and was easily replaced by much better data design, leading to much better code.
Usually some basic indexing is quite sufficient.
Your question is a good example of this:
The most important question is: how are you planning on processing this data? What is the actual goal that you are trying to achieve?

As other users have stated, it is generally not advisable to dynamically generate variable names from a string using eval. However, it is possible to do this with structure field names specifically.
