Example of subroutines to lift-off LM from the moon:

http://code.google.com/p/virtualagc/source/browse/trunk/Luminary131/BURN_BABY_BURN--MASTER_IGNITION_ROUTINE.s?r=258
# Filename:	BURN_BABY_BURN--MASTER_IGNITION_ROUTINE.s

and it contains interesting French phrases; anyone care to suggest its
meaning in this context?
see http://en.wikipedia.org/wiki/Honi_soit_qui_mal_y_pense):

# THE MASTER IGNITION ROUTINE WAS CONCEIVED AND EXECUTED, AND (NOTA
BENE) IS MAINTAINED BY ADLER AND EYLES.
#
# 		   HONI SOIT QUI MAL Y PENSE

And as expected storage is at a premium, see this comment:

# MOD NO. -- 0		TO COMPLETELY REWRITE THE DOWN TELEMETRY PROGRAM AND
DOWNLINK ERASABLE DUMP PROGRAM FOR THE
#			PURPOSE OF SAVING APPROXIMATELY 150 WORDS OF CORE STORAGE.
