integer RM = 50 
display("[c:50]", {"This text is centered"}) 
display("[c:RM]", {"This text is not centered"}) 
constant VC=graphcst:video_config() 
-- or 
RM = VC[VC_COLUMNS] 
display("[c:RM]", {"This text is not centered"}) 

Since it's a string anyway, you could use

display("[c:" & sprint(RM) & "]", {"This text is not centered"}) 

That's one way.

display("[c:" & sprint(RM) & "]", {"This text is not centered"}) 

Yeah, but doesn't that say This text is not centered when actually it is centered? scnr

On a slightly more serious note,

printf(1,">%6s<\n",{"four"}) -- produces ">  four<" 
printf(1,">%-6s<\n",{"four"}) -- produces ">four  <" 

Does anyone any have any suggestion/preference for a format string that would produce "> four <"?
(Obviously, there isn't one, but if I were to implement it what would feel right as the third alternative to "%6s" and "%-6s"? "%|6s"? "%=6s"?)

Thanks, unfortunately + is already in use on numbers to show a plus sign on positive values, so using that would mean you cannot centre numbers and/or break existing code.

Is there any preference for splitting say 7 spaces as 4:3 or 3:4?

Quick and Dirty:

-- add this at the end of std/console.e 
public sequence CS --Center text string  
public function CenterString(integer RM) 
--returns center string for the display routine, 
--given RM, the margin width 
return "[c:" & sprint(RM) & "]" 
end function 
----------------------------------------------------- 
-- test 
sequence text = "this is a test" 
CS = CenterString(25) 
display(CS,{txt})
