& pairs()
 
  Syntax: pairs(obj/attr)
 
  This function returns a string which lists the number of 'brackets' 
  in the specified attribute on the object.
 
  The string returned contains the number of { [ ( ) ] } in that 
  order.
 
  Error Messages:
  * If the attribute does not exist on the object the function 
  returns an empty string 
 
  Example:
  Given that #1234 is an object with the attribute COMMA.F on it:
> ex #1234/COMMA.F
COMMA.F: 
[ifelse(lt(strlen(round(%0,0)),4),round(%0,0),ifelse(lt(strlen(round(%0,0)),7),
[strtrunc(round(%0,0),[sub(strlen(round(%0,0)),3)])]%,[reverse(strtrunc(reverse(
round(%0,0)),3))],[strtrunc(round(%0,0),[sub(strlen(round(%0,0)),6)])]%,[reverse
(mid(reverse(round(%0,0)),3,3))]%,[reverse(strtrunc(reverse(round(%0,0)),3))]))]
