SWI to show register content

What would be the SWI to show the content (in decimal form) of a single register from some assembly executable ?
Would it be “OS_ConvertInteger4” followed by “OS_Write0” …or something more clever I missed out while scaning the SWI documentation ?

That’s the way I’ve done it before. Just make sure the buffer is big enough :)

Or you could try my Reporter which provides various SWIs to display single or multiple registers or text in a real-time scrolling window.
