Re: centering text on a field

[Joel Cochran <jrc@xxxxxxxxxx>]

Booth,

Here is the basic formula I use.  I'm writing this from memory but
should be pretty close.

<psuedo-code>
offset = ( %len( field ) - %len( %trim( field ) ) ) / 2 ;
field = %trim( field );
for i=1 to offset ;
  %replace( ' ' : field : 1 : 0 );
endfor ;
</psuedo-code>

Your mileage may vary depending on whether or not field is varying.  The
above is written where field is NOT varying.
