General Descrition:   This is an interactive program for 
                      computation of grades. The program
                      handles analysis of the grades 
                      (compute averages, final grades, 
                      etc.). GRADE uses the scores recorded by 
                      INPUT. Thus, the two programs and the 
                      data file are a complete system for
                      managing grade records.
 
Program Notes:        ALL INPUT/OUTPUT TO THIS PROGRAM SHOULD BE
                      IN UPPERCASE CHARACTERS.
                      This program is modified currently
                      for better output options like selection
                      of grade items to be displayed, actual
                      letter grade of the student, etc.
                      User's who need the new and updated
                      version are asked to contact the authors.
                      At the time of preparation of this DECUS
                      distribution tape the above additions 
                      are being tested.

A. INTRODUCTION
.p
This program analysis the grade data stored by INPUT program using
the data file ROSijk._DAT. Before using this program user should
have created/modified/updated the data file using the INPUT program.

B. SPECIFIC STRUCTURE AND USES
.p
The uses of the program are:
.list
.le ;Grades are used to compute statistics, set frequency distribution,
histograms, and to generate a list of final grades in three different
basis as follows:
.list
.display element RL,")"
.le ;Raw Scores, scores are taken as it is in the grade file.
.le ;Percentage of maximum possible score, all scores are
normalized to a basis of 100% and
.le ;Weighted percentage of final grade, scores are normailized to
a basis of percent of each grade with reference to total grade.
.end list
.le ;From the grouped grades above, eleven (or less) letter grade
cutoff's could be specified (A,A-,B+,B,B-,C+,C,C-,D+,D,E). This
cutoff ranges can be selected either in INPUT or GRADE program.
The advantage of selecting in the GRADE program is that one
can see the final distribution and statistics of grades
before choosing the cutoff points. 
.le ;Individual grades can be grouped to one or more subgroups and/or
total group (eg: sum of homeworks, quizzes, tests, etc.).
.le ;Records of students who dropped out during the middle of the
quarter/semester are still kept in the roster with a drop code, but
are not included in the computation of statistics. This record may
be useful when the student repeats the course next time.
.le ;Individual, subgroup and total group grades can be sorted as 
follows:
.list
.display elements RL,")"
.le ;Alphabetical order of names.
.le ;Increasing order of Social Security numbers, all the nine
digits or part of that (eg: last four digits) can be choosen
for this sort.
.le ;Decreasing order of individual grade, subgroup or total
group column totals. 
.end list

C. OUTPUT OPTIONS
.p
The output files from the roster file contains all the
entries of the grade components with the averages. Output
files are generated under two main catogeries, one with
a complete list of students names and social security 
numbers and the other with only the social security numbers
(or part of it) which can be posted for student verification.
Output files are of the form GRDijk._DAT and GSSijk._DAT.

D. HISTOGRAM
.P
The histogram of the program is generated on a Tektronix
type screen. If you are not running this program on
a graphics terminal or donot have a similar plotting
routine donot select this option.
