A Pascal Program to Marks the scores of students in three courses!

[Morris]

Note: to run the following program you need the following text files saved in the same directory as your program code.
mathans //this holds the examiners answer to math,should be arrange on one line,no space.
genans //this holds the examiners answer to Gen. Paper,should be arrange on one line,no space.
engans //this holds the examiners answer to english,should be arrange on one line,no space.
studentreceng //this holds students answers to english as well as their exam no. & name.
studentrecmath //this holds students answers to math as well as their exam no. & name.
studentecgen //this holds students answers to Gen.Paper as well as their exam no. & name.
studentscore // holds the output of student result....

here is the sample of file mathans.txt
ADBBE // this means five option

here is the sample of file studentrecmath

Take Note: this program marks result for 5 student,for 5 questions in three courses namely english,math,Gen.Paper..you can edit your code take as much student as possible....
