Hi everyone,

My program is meant to be / do:

A quiz about the bible ( < my teacher decided that <).
Using an array of records with a text file (working) it runs the quiz
and lets user print off their results at the end. each question must be on
a different screen, and possibly be randomized.

Yes, i have been through these boards and found other people have posted similar
threads, BUT, mine is unfortunately more complex thanks to my teacher's requirements.

Now, it is all working alright for now, i just would like to now how i could cycle through 12 different screens (each with it's own question), i would say using some loop or array loop?? you will see in my coding that it is FAR LONGER than it needs to be, and i could do it simpler.

Here is my code (for the UNIT that runs with it, the main program is fine :) )

UNIT Bible;

USES CRT, PRINTER, DOS;

CONST	  MaxQs = 12;						  
	  AnyKeyMessage = 'Press ANY KEY to continue';
      EndMessage = 'Are you sure you want to quit? (y/n): ';	  
	  BGColour = LightBlue; {BG and FG Colour are constants so they can be easily changed, } 
      FGColour = White; {without having to go through all the code.} 

TYPE Quiz = RECORD
        QNo : STRING[2];
        Answer : STRING[12];
        Hint : STRING[30];
        Question : STRING[45];
     END;	  

	 DataBase = ARRAY [1..MaxQs] OF Quiz;
	 
VAR QuizInfo : DataBase; Choice, UserChoice, AnyKeyIN : CHAR; Year,Month,Day,WDay : word;
    ACounter, LCounter, CorrectCounter, InCorrectCounter, Count : INTEGER; 
    HelpFile, QuizFile : TEXT; HelpInfo : STRING; UserAnswer : STRING[12];

	 AnyKeyIN := readkey;

	 BEGIN {WHILE}

As you can tell, too long, why all those procedures for each answer guess?, etc

Please note: I am programming in Turbo Pascal 5.5, not delphi :p

Any help will be GREATLY appreciated :)

The only difference between two UserGuess procedures is the index that is used for the QuizInfo array. You can use a single procedure for this, if you pass this index as a parameter to it. It's definition could be:

procedure UserGuessQ(QuestionNumber: Integer);

I'm sure this will get you on the right track.

Thanks pritaeas! That worked fine, the quiz runs in a single procedure now!
