This is a grade management program written by Ramu Ramanathan.  The Usage is:
grade  grdata   where grdata is a text file containing the following infor-
mation (the term 'test' is used here to denote tests or assignments):
First line:	Heading describing course, year, and quarter
Next line:	No of tests (nt)
Next line:	Points to be added to weighted average score - added[0]
Next nt lines:	weight[t]  maxscore[t] added[t] for t=1 to nt
['added' should initially be set to zero.  If you want to add points to
everyone, enter the value here.  If the class average falls below 67.5 percent,
the program will calculate points needed to be added and inform you, but no
points will be added.]
Next, one line for each student as follows:
lastname,firstname   idno  score[1]  score[2]  .... score[nt]
NOTE: no space after the comma in student's name
idno is the student's social security number or username
score[t] is the raw score in test number t BEFORE ANY POINTS ARE ADDED
Missing final exam scores must be entered as -99 and not as 0.  They will be ignored in
the computations.  To get a feel for what the program does, copy the following
commands and try them one by one:
  cp  /software/common/lib/xlib/grade.dat  grade.dat
  more grade.dat
  grade  grade.dat
