Debug variable addr contains the address of a StudentRecord data
structure in virtual memory.  The following code fragment is from this
file:

     CONST     MINGRADES   = 1;     MAXGRADES   = 10;
               MINSTUDENTS = 1;     MAXSTUDENTS = 5;
     TYPE
        GradeRange    = MINGRADES .. MAXGRADES;
        GradesArray   = ARRAY [ GradeRange ] OF integer;

        Class         = ( SENIOR, JUNIOR, SOPHOMORE, FRESHMAN );
        NameStr       = string[8];

        StudentRecord = RECORD
                          Name      : NameStr;
                          Id        : Integer;
                          Year      : Class;
                          NumGrades : GradeRange;
                          Grades    : GradesArray;
                        END;
