What is the result of the code: initialize global count to 0
When screen1 initialize
set global count to 1
while test get global count <= 5
set global count to get global count + 1
set lalbel text to the value of count is :: get global count
Label 1 will update on Screen 1 to show "The value of count is :: 5
