Israel,

	I could not send you mail, the NeXT mail agent had a problem
	with it.

	My question is,

		How can my application intercept the open call and
		interpret the redirected output?

	I have seen this in many PS interpreters like PreScript.

	You sent the output to LPT1.OS2 and the interpreter immediately
	begins capturing it and interpreting it for output to the
	destination printer.

	I want to know how my application can do this.  I want it to
	know immediately when the output has been sent and then start
	reading it in.  Checking for the existence of the file is 
	obviously very inefficient.

	Thanks...Regards |(8>
