Not sure what you are actually trying to do, but instead of using  a browse
to display the details, you could create an array and read in the field data
wanted and then put up a listbox.  You could put in a "line number" which
would be the index # of the array.

Your user could then enter a line #, and you could then manipulate the data
any way you want.

If you do use this method, you might want to have a second array which holds
the record #'s of the records read.  You can then use the record # lookup to
either get more information of for posting back to that record.

If you just want your user to be able to change a value in the detail file
from the browse, you can create a screen with the necessary field and use
@br to allow you to popup the screen over the field value to be changed.
Again, I would grab the record # of the detail to use in posting the new
value to that detail.  Re-execute the browse and the new value will be
displayed.
