Rolf has left a new comment on your post "Solutions to the Exercises in Episode 4":
The global $?BLOCK variable you're using in the exception rule is only introduced in Episode 5 of this tutorial. As a result, your solution to implementing the try statement can't be easily applied to the code I have after Episode 4. By removing the 2 lines referencing $?BLOCK, I get some working code, but I'm not quite sure whether it's also correct. Posted by Rolf to Parrot at January 2, 2009 2:00 PM
