This is exactly why God made objects. (Well, one
of the *many* reasons, but certainly one of the
most practical.) Write yourself a little compound
widget/object that sets it's own label in units
of 5. You could use a program like FSC_Inputfield
as a rough example:

Be careful, though. Once you see how powerful objects
are, and how easy to write, things will never be the
same and your employer will expect even bigger things
from you. :-(

Cheers,

David
