Center a string with %format?
|
Is it possible to center a string somehow? For example, I want the total width of the string to be 60 characters, so if the string is:
"BrandonNC" then the output would be:
"__________________________BrandonNC_________________________" or something similar (with spaces of course). |

Not that I know of, but I have a function that works just as well.
| Code: |
<?xml version="1.0" encoding="ISO-8859-1" ?>
<cmud>
<func name="padcent" copy="yes">
<value>$Res=%repeat($Character,$Length)
$Res=%insert($String,$Res,(($Length-%len($String))/2)+1)
$Res=%left($Res,$Length)
#RETURN $Res</value>
<arglist>String, Length, Character</arglist>
</func>
</cmud>
|
The syntax is @padcent("string","Whole length of field","character you wish to fill in empty space")
So, in your example, you'd do:
#SAY {@padcenter("BrandonNC","60"," ")}

Here's another variation. This version can only pad with spaces, rather than with an arbitrary character.
| Code: |
$string="your string"
$totalLength=60
$pos = ($totalLength+%len($string))/2
#print {%format(&${pos}s,$string)} |

I finally got it with %format:
%format("&35s&-35s",%left(@Name, %len(@Name) / 2), %right(@Name, %len(@Name) / 2))
where @Name is "BrandonNC" or whatever. outputs a 70 character string with spaces on either end... (35 + 35) |
