# PROGRAM P-31 DESCRIPTION **
#
# 1. TO ACCEPT TARGETING PARAMETERS OBTAINED FROM A SOURCE EXTERNAL
# TO THE LEM AND COMPUTE THERE FROM THE REQUIRED-VELOCITY AND
# OTHER INITIAL CONDITIONS REQUIRED BY LM FOR DESIRED MANEUVER.
# THE TARGETING PARAMETERS ARE TIG (TIME OF IGNITION), TARGET
# VECTOR (RTARG), AND THE TIME FROM TIG UNTIL THE TARGET IS
# REACHED (DELLT4), DESIRED TIME OF FLIGHT FROM RINIT TO RTARG.

# ASSUMPTIONS **
#
# 1. THE TARGET PARAMETERS MAY HAVE BEEN LOADED PRIOR TO THE
# EXECUTION OF THIS PROGRAM.
# 2. THIS PROGRAM IS APPLICABLE IN EITHER EARTH OR LUNAR ORBIT.
# 3. THIS PROGRAM IS DESIGNED FOR ONE-MAN OPERATION, AND SHOULD
# BE SELECTED BY THE ASTRONAUT BY DSKY ENTRY V37 E31.
