You put the data to be centered in a field and pass the field. It returns it centered. You shouldn't have to tell the procedure the length of the field, it can figure it out.

How would the procedure know what length to center your character in, if you didn't in some way tell the procedure the size of the field that you want to hold the centered text?

It seems to me that with a procedure to center a field, descriptors are the
only way to go. You need to be able to pass any size character field. You
would not want to center a numeric field, nor a constant, only character
fields. So you only have to get the size of a character field. The user
should not have to pass the size of the field.

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.
