If precision placement is important to you, you can create a variable form
(that looks a lot like a pause command), and set a variable for it to
display as the message. Some more tools you can use:
-- CVAL('SCREENSIZE') for your total screen dimensions width, height
set var vScreenSize = (cval('screensize'))
set var vScreenWidth = (ssub(.vScreenSize,1))
SET VAR vScreenHeight = (SSUB(.vScreenSize,2))
-- for your underlying form/dialog/process control console:
GETPROPERTY RBASE_FORM LEFT 'varFormLeft'
GETPROPERTY RBASE_FORM TOP 'varFormTop'
GETPROPERTY RBASE_FORM HEIGHT 'varFormHeight'
GETPROPERTY RBASE_FORM WIDTH 'varFormWidth'
-- for your faux PAUSE form:
PROPERTY RBASE_FORM LEFT 'varCalcedPauseLeft'
PROPERTY RBASE_FORM TOP 'varCalcedPauseTop'
PROPERTY RBASE_FORM HEIGHT 'varCalcedPauseHeight'
PROPERTY RBASE_FORM WIDTH 'varCalcedPauseWidth'
