Exercise 4: Storage Method

After reviewing this code, you can return to Hands-On Exercise 4.

1. Using VS Code - ObjectScript, change the top line of ObjectScript.DataEntry3 to ObjectScript.DataEntry4, and save it as ObjectScript.DataEntry4.

2. Edit Main() so that it calls Store() after calling Display(), also passing answers.

   
   Class ObjectScript.DataEntry3
   {
   
   /// Main loop section
   ClassMethod Main()     
   {   
       while ..Prompt(.answers) {       
           do ..Display(answers)
           do ..Store(answers)
       }
   }
   
   }

   

3. In ValidPhone(), just after the line that adds the default area code, add an If that uses $Data to check if the phone exists in the index already; if it does, return 0.

   
           set:($match(phone, "\d{3}-\d{4}")) phone = "617-" _ phone  // add default area code
           // is phone already taken?
           if $data(^PersonI("Phone", phone)) {
               write !, "Phone number already in use"
               return 0
           }
   

   

4. Copy the new Store() method into the class at the bottom.

5. Click the Save and Compile buttons.

6. Start the Terminal, and run your method, by typing do ##class(ObjectScript.DataEntry4).Main().
