This directory holds an example of a simple form-handling CGI program.
The program displays student grades given a student's name and social
security number. 

Files:
 
form.html - a HTML form that can be used to submit queries to the
            getgrades CGI program.

betterform.html - another HTML form, this one is formatted using an
	          HTML table and looks a little better.

handleform.c - The source code for the CGI program. THe program validates
               requests (makes sure each field is entered) and then
               generates some random grades and sends them back as HTML.

cgilib.c - source code for some CGI support routines, including the
	decoding of urlencoded requests.

runfromshell - a schell script that sets up environment variables so
	that the CGI program can be tested from the command line.
