Hi,<BR>
<BR>
Here is a simplified example of the problem I am having:<BR>
I open the following in DrScheme:<BR>
<BR>
<BR>
#lang scheme<BR>
(define (string-eval str) (eval (read (open-input-string str))))<BR>
(define (:Object-new c)<BR> (new (string-eval c))<BR> )<BR>
(define entity% (class object%<BR> (field (Colour: "Red"))<BR> (super-new)<BR> )<BR> )<BR>
(define point% (class entity%<BR> (field (X: 0.0))<BR> (field (Y: 0.0))<BR> (field (Z: 0.0))<BR> (super-new)<BR> )<BR> )<BR>
(define aa (:Object-new "point%"))<BR>(define ab (:Object-new "entity%"))<BR>
<BR>
<BR>
When I run it, it comes up with the following error:<BR>
<BR>
compile: unbound identifier (and no #%top syntax transformer is bound) in: point%<BR>
<BR>
but then when I enter the last two lines into the interactions window, directly after the error, it works:<BR>
<BR>
> (define aa (:Object-new "point%"))<BR>(define ab (:Object-new "entity%"))<BR>> aa<BR>#(struct:object:point% ...)<BR>> ab<BR>#(struct:object:entity% ...)<BR>
<BR>
Why does it work one time & not the other??<BR>
<BR>
Any help would be appreciated.<BR>
<BR>
Thanks<BR>
<BR>
Tim.<BR>
