visit = visit + 1 ………………………………………………………………………...…. (3)
If the PatientID is zero, or the PatientID, visits and/or any of the weights (i.e., weight and average
weight) is negative an appropriate error message is displayed; otherwise it searches for this PatientID in
the text-file and update their record as described earlier. Also, if the PatientID is not found an
appropriate error message is displayed, as shown by the test run below:
