busydialog=CreateObject("roOneLineDialog")
busydialog.SetMessagePort(screen.GetmessagePort())
busydialog.SetTitle("All I do is think and blink.") 'credit from "I dream of Jeannie"
busydialog.ShowBusyAnimation()
busydialog.Show()

When you're done, use busydialog.Close()

If you are wanting to close the busy animation in a different routine, such as a secondary poster screen, the reference needs to be passed to it - for example -

sub....routine....code...
...blah.blah.blah...
busydialog=CreateObject("roOneLineDialog")
busydialog.SetMessagePort(screen.GetmessagePort())
busydialog.SetTitle("All I do is think and blink.") 'credit from "I dream of Jeannie"
busydialog.ShowBusyAnimation()
busydialog.Show()
ShowPosterScreen2(busydialog)
...rest of current subroutine code...
...end sub

Sub ShowPosterScreen2(busydialog=invalid) 'sets default value to invalid, which allows you to call the routine without the busydialog object required
If type(busydialog<>"Invalid") Then busydialog.close() ' best to stick this line in after the new content parsing is complete.
...sub code here...
End Sub

When you type this in does anything happen for you?

busydialog=CreateObject("roOneLineDialog") ' creates a dialog box
busydialog.SetMessagePort(screen.GetmessagePort()) 'sets a message port for the dialog box
busydialog.SetTitle("All I do is think and blink.") 'displays a line of text for the dialog box title
busydialog.ShowBusyAnimation() ' enables a spinning animation
busydialog.Show() ' makes the dialog box and busy animation display

busydialog.Close() ' makes the busy animation and dialog box 'go away'

I don't understand how to make it any more clearer. 🙂
You probably don't need a message port, since you're not monitoring any messages for it. And the title can be left blank too if you just want the spinning animation and nothing else.

busydialog=CreateObject("roOneLineDialog") ' creates a dialog box
busydialog.ShowBusyAnimation() ' enables a spinning animation
busydialog.Show() ' makes the dialog box and busy animation display

That should be the minimalist approach.
