[Bug fortran/23232] New: DATA implied DO variables

[rofi at ya dot com]

gcc version 4.1.0 20050730 (experimental)

The following two DATA statements are rejected by gfortran because "J" is not
considered a valid primary in those expressions although it is the variable of
another enclosing data-implied-do.

 PROGRAM p
  REAL :: ONE_ARRAY(100, 100)
  INTEGER :: K, J

  DATA ((ONE_ARRAY (K, J), K = 1, J-1), J = 1, 100) /4950 * 1.0/
  DATA ((ONE_ARRAY (K, J), K = J, 100), J = 1, 100) /5050 * 0.0/
 END PROGRAM

$ gfortran -fsyntax-only snippet.f90
 In file snippet.f90:5

  DATA ((ONE_ARRAY (K, J), K = 1, J-1), J = 1, 100) /4950 * 1.0/
                                1
Error: Variable 'j' at (1) cannot appear in an initialization expression
 In file snippet.f90:6

  DATA ((ONE_ARRAY (K, J), K = J, 100), J = 1, 100) /5050 * 0.0/
                             1
Error: Variable 'j' at (1) cannot appear in an initialization expression
