1983 US DOD Reference Manual for the Ada Programming Language w/Comb Binding
I can\'t guarantee what year this copy was actually printed, because they might not have changed anything for several years when printing out copies on demand. But it sure seems 1980s period-correct to me, and I was programming professionally then. My employer even had a comb-binding setup where we\'d bind our engineering reports and user manuals this same way, ourselves.
Good used condition. Zoom in on my sharp photos for details. The comb binding has one prong curled up, visible in some of the photos, including the photo of it on the postage scale. Rear cover is not pristine.
I was a mechanical engineer whose career was mostly in software. I programmed in at least a dozen languages, but thankfully not this one. But I knew enough to scoop this manual up and find a good home for it, when I stumbled across it.
