Ada code that is similar to FORTRAN's namelist?

Ada code that is similar to FORTRAN's namelist?

Has anyone written ada code that will read data from a file in
a manner similar to FORTRAN's namelist?

Yes.

I wrote such a package -- I call it Name_IO, and it is available on the
PAL library.  Take a look at 

languages/ada/swcomps/woodruff.zip:
  File Name                 Size
  ---------                 ----
  woodruff.zip            54,875

The file woodruff.zip contains the following files:
  readme.txt -- introduction
  support.src -- pager2 source of support routines from New Abstractions
              -- COMPILE THIS FIRST
  main.src    -- pager2 source of the Woodruff Collection
              -- COMPILE THIS SECOND
  testprog.src -- test program Test_Name_IO
  data.src     -- data file used by Test_Name_IO

The briefest possible summary is:

  Name_IO implements name-directed input in a generic package.  
The package is able to deliver values bound to variables from an input
stream that looks like:
      A = 1.0 ;               		 	a floating scalar
      V := 3, 4, 5 ;				 a three-vector
      Filename => "Test.dat;2" ;		 a string
      Enum  = Users_Enumerated_Constant ;	 Enumeration value
  
Hope this is useful to you.
