I don't understand how data files work . I've read the tutorial but I still don't get it. How do you create a new file and then open it. For example I need to create a program that records your score. So you can see your score after. Can someone explain how to do a program like that? I'm extremely confused Here's the code type high_type: record street:string(7) name:string score:int end record var high: array 1..5 of high_type for i:1..5 high(i). street:= "Laurier" high(i). name:= "Anna" high(i). score:=100 end for var f1:int open:f1, "Read Data", write for i:1..5 write: f1, high(i) end for close: f1 open : f1, "Reid_Data", read for i : 1 .. 5 read : f1, high (i) end for close :f1 |

When you use open: filenumber, filename, put you create the file and can now put information in it. then you put :fn , name - 1200 and it will record the score. then you just read the ile and put it on the screen to view text files. |
