# Purpose: This is code written from the flowchart on p. 33 of
# E-2065, which is a document titled "Block II AGC
# Self-Check and Show-Banksum", by Edwin D. Smally.
# Mod history: 07/07/04 RSB. Began.
#
# Similar code was apparently originally in Luminary and/or Colossus,
# but much of it was removed over the course of time to make more room.
# I don't know what the original code was like, but the flowcharts still
# exist, so I've rewritten the code from the flowcharts.
# P. 33 of Smally.
