length of the string

When I re-read this I remembered why I leant in this direction.  Unless you are
asking the programmer to only receive the centered result into the original
input field or into a field of identical size (both of which require the kind of
knowledge of the routine that you are trying to avoid) you cannot use an Eval'd
function for a generic centering routine unless a) you have one routine for each
possible length of output field - again requiring knowledge or b) Use CallP and
pass the output field as a parameter and use descriptors to work out how long it
is.

The original example used Eval and so I went with that direction.
