Expected 'While' or 'Until'

You created a Do loop, but did not include the associated While or Until keywords. The test condition of a Do loop requires either a While or an Until keyword in the test condition statement. The following demonstrates the correct structure of a Do loop.


                      Do [{While | Until} condition]
   [statements]
   [Exit Do]
   [statements]
Loop 

Or, you can use this syntax:


                      Do 
   [statements]
   [Exit Do]
   [statements]
Loop [{While | Until} condition]

To correct this error

  • Make sure that the Do loop includes all the necessary parts.
