Which is what I do in these sorts of discussions, at least if it has not been specified previously, and especially when dealing with larger docs. E.g. from my previous messages in this thread:

	ref: pdfPg.152,etc of http://www.bitsavers.org/pdf/dec/pdp11/1124/MP01018_1124schem_Aug80.pdf

	pdfPg.30 of http://www.bitsavers.org/pdf/dec/pdp11/1124/MP01018_1124schem_Aug80.pdf

(The latter being the page for the H777 I was mistakenly looking at.)

Makes it easier for a recipient, everyone following, and yourself if you have to go back to it in the course of subsequent discussion.
