I need help with a program for school. I am a very novice pascal programmer. I need to allow the person using the program to add a record and then search for it and view it. Currently, whenever I add a record via the program and try to search for it and view it, the same record shows up.

This first program is the program I used to create the file.

        PROGRAM SpellingBeeFile;

           USES
              CRT, SYSUTILS;

           TYPE
              TestRec = RECORD
                           TestNo      : LONGINT;
                           Word        : ARRAY[1..10] OF STRING[15];
                           Definition  : ARRAY[1..10] OF STRING[40];
                        END;

              TestFileRqd = FILE OF TestRec;

           VAR
              Test : TestRec;
              TestFile : TestFileRqd;

           PROCEDURE InitialFile;
              BEGIN
                 ASSIGN(TestFile,'C:\TestFile.dta');
                 REWRITE(TestFile);
                    WITH Test DO
                       BEGIN
                          Test.TestNo := 1;

                          Word[1] := 'hectare';
                          Definition[1] := 'unit of area';

                          Word[2] := 'active';
                          Definition[2] := 'being busy';

                          Word[3] := 'amaze';
                          Definition[3] := 'surprise';

                          Word[4] := 'bound';
                          Definition[4] := 'leap and jump';

                          Word[5] := 'cavern';
                          Definition[5] := 'a large cave';

                          Word[6] := 'difficult';
                          Definition[6] := 'hard to do';

                          Word[7] := 'frozen';
                          Definition[7] := 'turned to ice';

                          Word[8] := 'garage';
                          Definition[8] := 'building for a car';

                          Word[9] := 'jaguar';
                          Definition[9] := 'large cat';

                          Word[10] := 'lemonade';
                          Definition[10] := 'fizzy drink'; 
                          WRITE(TestFile, Test);
                       END;
                 CLOSE (TestFile);
              END;

           BEGIN
              InitialFile;
           END.

This is the program used to maintain the file created by the first program.

           USES
              CRT, SYSUTILS;

                           Word        : ARRAY[1..10] OF STRING[15];
                           Definition  : ARRAY[1..10] OF STRING[40];
                        END;

              TestFileRqd = FILE OF TestRec;

           VAR

I have made bold the two procedures that are most likely to be causing this. Thank you in advance for the help

I tried to bold the procedures but it did not work. Procedures 'TestSearch' and 'AddTest' are the procedures in question. They are in the second program

In the TestSearch procedure you SEEK to the last record in the file but you don't read that record before checking the Test.TestNo

Thanks so much but I figured out what was wrong. In testsearch, I call for display test and in displaytest, there is a READ which moves the file pointer to the next record and so displays a different test.
