Hands-On Exercise 4

Add editing capabilities to your myBASlookup routine:

• Add code to main to call a new subroutine called edit once the user has made a choice from the list of matches.

• The edit subroutine should lock the record chosen for editing. Then it should call: load, reprompt, and update. After the update, unlock the record.

• The load subroutine simply loads the person's data. Update the display subroutine to call this new subroutine.

• reprompt is a function. It should mimic the myBASdatent prompts and use its “valid” functions, but also display the current (old) data inside the prompts. It should return True if changes were made.

• If changes were made, the update subroutine should start a transaction, and store the new data in ^PersonD. Next, it should update ^PersonI. Updating an index means: using Erase() on the old entry in the index and adding the new entry.
