Exercise 2: Second Data Entry Class

Click here to return to the exercise description in the main part of the tutorial.

1. Using VS Code - ObjectScript, change the top line of ObjectScript.DataEntry1 to ObjectScript.DataEntry2, and save it as ObjectScript.DataEntry2.

2. Write the Prompt() method so that it contains the prompts.

   
   Class ObjectScript.DataEntry2
   {
   /// prompt until user doesn't enter a name
   ClassMethod Prompt() as %Boolean [Publiclist = (name, phone, dob)]
   {   
       read !, "Name: ", name
       return:(name = "") 0  // user entered nothing so return FALSE and exit method
       read !, "Phone: ", phone
       read !, "DOB: ", dob
       return 1  // return true
   }
   }

   

3. Below Prompt(), write the Display() method so that it contains the display code.

   
   Class ObjectScript.DataEntry2
   {
   // this is where the Prompt() method is
   
   /// display the data
   ClassMethod Display() [Publiclist = (name, phone, dob)]
   {   
       write !!, "========================================"
       write !, "Name:", ?20, name
       write !, "Phone:", ?20, phone
       write !, "DOB:", ?20, dob
       write !, "========================================", !
   }
   }

   

4. Above Prompt(), write the Main() to loop and call the other two methods.

   
   Class ObjectScript.DataEntry2
   {
   /// Main loop section
   ClassMethod Main()    
   {   
       while ..Prompt() {
           do ..Display()
       }
   }
   
   // this is where the Prompt() method is
   }

   

5. Click the Save and Compile buttons.

6. Start the Terminal, and run your method, by typing do ##class(ObjectScript.DataEntry2).Main().
