## Copyright:	Public domain.
## Filename:	TAGS_FOR_RELATIVE_SETLOC.agc
## Purpose:	Part of the source code for Colossus, build 249.
##		It is part of the source code for the Command Module's (CM)
##		Apollo Guidance Computer (AGC), for Apollo 9.
## Assembler:	yaYUL
## Reference:	pp. 25-33 of 1701.pdf.
## Contact:	Ron Burkey <info@sandroid.org>.
## Website:	www.ibiblio.org/apollo.
## Mod history:	08/02/04 RSB	Adapted from similar Luminary 131 file.
##		05/06/09 RSB	Made a few comment corrections I noticed
##				were needed when adapting for Comanche 055.
##		2017-01-05 RSB	Page numbers now agree with those on the
##				original harcopy, as opposed to the PDF page
##				numbers in 1701.pdf.
##		2017-01-20 RSB	Cross-diff'd comment text (not whitespace)
##				vs the already-proofed corresponding Colossus
##				237 and Comanche 55 source-code files
##				and corrected errors found.
##		2021-05-30 ABS	Removed four lines not present in scans.

## The contents of the "Colossus249" files, in general, are transcribed 
## from a scanned copy of the program listing.  Notations on this
## document read, in part:
##
##	Assemble revision 249 of AGC program Colossus by NASA
##	2021111-041.  October 28, 1968.  
##
##	This AGC program shall also be referred to as
##				Colossus 1A
##
##	Prepared by
##			Massachusetts Institute of Technology
##			75 Cambridge Parkway
##			Cambridge, Massachusetts
##	under NASA contract NAS 9-4065.
##
## Refer directly to the online document mentioned above for further information.
## Please report any errors (relative to the scanned pages) to info@sandroid.org.
##
## In some cases, where the source code for Luminary 131 overlaps that of 
## Colossus 249, this code is instead copied from the corresponding Luminary 131
## source file, and then is proofed to incorporate any changes.
