I am in the process of linking a high level language (pop11) to NeWS.
Abitrary PostScript code can be sent from the client to the server. The problem is that what is the best way to catch any errors in the postscipt
code down loaded. I can think of two posible ways of doing this.

1.	Down load the code in the context of a stopped opperator and 
	return to the client the error condition.

2.	Put error handlers in errordict that do not call stop and modify
	handleerror to report the error to the client.

Which method have other people used? Are there any other ways of catching
errors? Example code would be most welcome.
