Of course it prints 5. The 'i' in the do-loop has the scope of
the implied-do-loop. The 'I' in the program has the scope of the
program.
laptop:kargl[247] cat ui.f90
integer j(4)
I=5
j = 42
j = (/(i,i=1,I-1)/)
print '(A,I0,A,4(I0,1X))', 'I = ', I, ' j = ', j
end
laptop:kargl[248] gfc4x -o z -fdump-tree-original ui.f90
laptop:kargl[249] ./z
I = 5 j = 0 134516008 0 0
The question becomes whether the 'I' in the implied-do-loop is
being used uninitialized.
