Symbols are values (just like strings, numbers, etc). Identifiers are not values, but thigns that can be bound to values. The request below combines the two, as if they were the same thing.
While it is possible to do things that approximate what you want, most programming problems can be solved without them (and they often bring in complexity that you don't really want to deal with). How about using a hash table instead? You can say: (define my-hash (make-hash)) and then when you would have written (set! number3 3) you isntead write (hash-set! 'number3 3) and this will also work: (hash-set! (string->symbol (format "number~a" 3)) 3) And when you would have said number3 to get the current value bound to that identifier, you instead say: (hash-ref my-hash 'number3) hth, Robby On Thu, Mar 10, 2011 at 5:28 PM, Brian Moriarty <[email protected]> wrote: > Hello!
