I'm a total n00b when it comes to scheme, but I do know that symbol- 
 >string and string->symbol allow you to convert
symbols to strings and strings to symbols respectively. Take this  
example:

 > (symbol->string 'x)
"x"
 > (string-length (symbol->string 'x))
1
 >
 > (symbol? (string->symbol "hello"))
#t

Hope this helps.
