Is there any functionality in IDL that will allow it to evaluate a a string as code?

Or, failing that, is there a nice, dynamic way of including /KEYWORD in functions? For example, if I wanted to ask them for what type of map projection the user wants, is there a way to do it nicely, without large if/case statements for the /Projection_Type keyword it needs?

With even a small number of user options, the combinations would cause if/case statements to get out of hand very quickly to handle all the possible options.
