Apollo-11/Luminary099/EXTENDED_VERBS.agc

# Copyright:	Public domain.
# Filename:	EXTENDED_VERBS.agc
# Purpose: 	Part of the source code for Luminary 1A build 099.
#		It is part of the source code for the Lunar Module's (LM)
#		Apollo Guidance Computer (AGC), for Apollo 11.
# Assembler:	yaYUL
# Contact:	Ron Burkey <info@sandroid.org>.
# Website:	www.ibiblio.org/apollo.
# Pages:	262-300
# Mod history:  2009-05-10 SN   (Sergio Navarro).  Started adapting
#				from the Luminary131/ file of the same
#				name, using Luminary099 page images.
#		2009-06-05 RSB	Corrected 5 typos.
#		2009-06-06 RSB	Eliminated an extraneous 3-instruction block
#				and added a missing instruction.
#		2009-06-07 RSB	Added a couple of "SBANK=" for compatibility
#				with yaYUL. Corrected a typo.
#		2010-12-31 JL	Fixed page number comments.
#		2011-01-06 JL	Added missing comment characters.
#		2011-05-08 JL	Flagged SBANK= workarounds for future removal.

# This source code has been transcribed or otherwise adapted from
# digitized images of a hardcopy from the MIT Museum.  The digitization
# was performed by Paul Fjeld, and arranged for by Deborah Douglas of
# the Museum.  Many thanks to both.  The images (with suitable reduction
# in storage size and consequent reduction in image quality as well) are
# available online at www.ibiblio.org/apollo.  If for some reason you
# find that the images are illegible, contact me at info@sandroid.org
# about getting access to the (much) higher-quality images which Paul
# actually created.

# Notations on the hardcopy document read, in part:
