Dear Mark,
'illegal use of nesting marker'
This is one of those issue a Mozart user must learn to deal with, and
it took me a while too :) The nesting marker $ simply indicates a
return value from within some nested construct. You can always avoid
using a nesting marker, by using explicit variables instead. Here is
an example.
X = {MyObject get($)}
can be written as
{MyObject get(X)}
Sometimes you may need to introduce an additional variable.
Best
Torsten

Hi,
I've attempted to design a graphical interface to allow input of a
partial sudoku puzzle.
I have created handles using the feature:..... method so that I can
dynamically name the handle of each number box.
The function below is called 9x9 times (a function calls this one 9
times, then another calls that 9 times)to create 81 entry+list
boxes. The handles for each entry and listbox pair are 'E1' 'L1' ,
'E2' 'L2' , etc up to, 'E81' 'L81'
fun {NumEnt X}
lr(entry(init:"" feature:{String.toAtom &E|{Int.toString X}}
glue:nsew width:3)
dropdownlistbox(init:[1 2 3 4 5 6 7 8 9]
feature:{String.toAtom &L|{Int.toString X}}
action:proc {$}
{Desc.{String.toAtom &E|
{Int.toString X}} set(Desc.{String.toAtom &L|{Int.toString X}} get
($))}
end
))
end
The problem I am having is defining the action parameter for the
dropdownlistbox - namely that it should update it's associated
entry box. The error I am getting is an 'illegal use of nesting
marker' which I've tracked down to the get($) function. Trouble is
I can't see any other way to do this.
Any help would be great!
