On ALGOL Education: Automatic Grading Programs
Two ALGOL grader programs are presented for
the computer evaluation of student ALGOL programs. 
One is for a beginner's program; it furnishes random data
and checks answers. The other provides a searching 
test of the reliability and efficiency of an integration
procedure.  There is a statement of the essential 
properties of a computer system, in order that
grader programs can be effectively used.
