of the x11 based games. I'm not going to tag the originals with bsd_44_lite and do this in two stages since it's just not worth it for this collection, and I've got directory renames to deal with that way. Bleah. Submitted by: jkh

** On-Board Computer
|
|
**
|
|
** A computer request is fetched from the captain. The requests
|
|
** are:
|
|
**
|
|
** chart -- print a star chart of the known galaxy. This includes
|
|
** every quadrant that has ever had a long range or
|
|
** a short range scan done of it, plus the location of
|
|
** all starbases. This is of course updated by any sub-
|
|
** space radio broadcasts (unless the radio is out).
|
|
** The format is the same as that of a long range scan
|
|
** except that ".1." indicates that a starbase exists
|
|
** but we know nothing else.
|
|
**
|
|
** trajectory -- gives the course and distance to every know
|
|
** Klingon in the quadrant. Obviously this fails if the
|
|
** short range scanners are out.
|
|
**
|
|
** course -- gives a course computation from whereever you are
|
|
** to any specified location. If the course begins
|
|
** with a slash, the current quadrant is taken.
|
|
** Otherwise the input is quadrant and sector coordi-
|
|
** nates of the target sector.
|
|
**
|
|
** move -- identical to course, except that the move is performed.
|
|
**
|
|
** score -- prints out the current score.
|
|
**
|
|
** pheff -- "PHaser EFFectiveness" at a given distance. Tells
|
|
** you how much stuff you need to make it work.
|
|
**
|
|
** warpcost -- Gives you the cost in time and units to move for
|
|
** a given distance under a given warp speed.
|
|
**
|
|
** impcost -- Same for the impulse engines.
|
|
**
|
|
** distresslist -- Gives a list of the currently known starsystems
|
|
** or starbases which are distressed, together with their
|
|
** quadrant coordinates.
|
|
**
|
|
** If a command is terminated with a semicolon, you remain in
|
|
** the computer; otherwise, you escape immediately to the main
|
|
** command processor.
