when sent a message, the target can't find itself!

The catch is that the handler has no advance knowledge of what field
or card it can be called from--I'm trying to make something generic
that can add a currency formatted value to a field that already
contains a currency formatted value.

In several places, the names of the fields are actually being
constructed by string manipulation (e.g., val_sbt comes from [ fldNam
& "_sbt"  ], and then I want to add the $123.45 in val (or possibly
fld fal) to the $852.87 already in fld_sbt.)

And then, when I"m done on the page, I have to add fld_sbt to a
totalling field on yet another page.

So the solution *seems* to be to send a message to the field to add
something to itself.  But the handler only knows the name by "the
target", and it seems to take several lines of code to parse a long
name into a card X and Field Y.

My real need is the very narrow issue of a handler pulling the value
of the field that called it, and then putting something back in.  It
seems that this should take one line of code, not 8 or 10.
