Q: listing form parameters

I'm using Forms [32 Bit] Version 10.1.2.2.0 (Production)

I wish to create a general purpose procedure to list an fmb's parameter
names and values, but I don't see how to do that.  Does anyone know how to
do that?

To be more specific in case my meaning isn't clear... an example of a
general purpose procedure to access the items in a block, I could use code
such as (of the top of my head, totally untested code)

  item_name := get_block_property('THE_BLOCK',FIRST_ITEM);
  last_name := get_block_property('THE_BLOCK',LAST_ITEM);
  while 1=1
  loop
    the_value := name_in('the_block.'||item_name);
    message(item_name||'='||the_value);
    if item_name = last_item then exit; end if;
    item_name := get_item_property(item_name,NEXT_ITEM);
  end loop;

I want to do something similar to the above, but listing the forms
parameters and their values.  If I know the name of a parameter then I can
get the value using NAME_IN('PARAMETER.THE_NAME'), but I am stuck on how
to get a list of the names in the first place.

Feedback appreciated.

Thanks, malcolm dj.
