Some time ago I set up some variables to use in the pause command so that I 
could position the display in regular places as well as simply the default of 
central.

As far as I know, top right, top left, bottom right and bottom left work fine.

What I want now is top (and bottom) central but I can’t find a way to make it 
work. And, presumably, for left and right central I would simply reverse the 
co-ordinates with appropriate adjustments.

Looking at what I originally set up in my variables I left out whichever one 
was the central parameter, eg: for vPos_Top_Left I use | TOP 10 | LEFT 10 and 
for vPos_Top_Centre I thought | TOP 10 | would work.

I do realise that I can position the display “manually” by trial and error with 
the correct number of pixels from the left but is there a way to let R:Base do 
the central positioning automatically?

Any guidance gratefully appreciated.
Regards,
Alastair.
