fortran syntax eorr while using DATA statement to initialize an array

Question

I encountered the following Fortran code which cannot be compiled using gfortran:

  CHARACTER(LEN=20) :: filename(max_xoms,2)
  DATA(filename = RESHAPE(SOURCE=(/'XobsXOM0.txt','XobsXOM1.txt','XobsXOM2.txt','XobsXOM3.txt','XobsXOM4.txt',  &
                                   'XobsXOM5.txt','XobsXOM6.txt','XobsXOM7.txt','XobsXOM8.txt','XobsXOM9.txt',  &
                                   'XobsXOS0.txt','XobsXOS1.txt','XobsXOS2.txt','XobsXOS3.txt','XobsXOS4.txt',  &
                                   'XobsXOS5.txt','XobsXOS6.txt','XobsXOS7.txt','XobsXOS8.txt','XobsXOS9.txt'/),  &
                                   SHAPE=(/max_xoms,2/)))

The makefile that comes with the code uses ifort. I changed the compiler to gfortran and got an error message while compiling the above:

gfortran  -c -fbacktrace -ffree-line-length-none -Wall hype_indata.f90
hype_indata.f90:48.16:

  DATA(filename = RESHAPE(SOURCE=(/'XobsXOM0.txt','XobsXOM1.txt','XobsXOM2.txt'
                1
Error: Syntax error in DATA statement at (1)

I've tried removing = at 1, but that doesn't fix the statement.

Can anyone please explain how should I fix this statement?

Thanks

BTW, gfortran --version returns:

GNU Fortran (tdm64-2) 4.8.1

if max_oms is a parameter (i.e. a constant, and it probably is one) you can do:

CHARACTER(LEN=20) :: filename(max_xoms,2) = RESHAPE(SOURCE=(/'XobsXOM0.txt','XobsXOM1.txt','XobsXOM2.txt','XobsXOM3.txt','XobsXOM4.txt',  &
                                   'XobsXOM5.txt','XobsXOM6.txt','XobsXOM7.txt','XobsXOM8.txt','XobsXOM9.txt',  &
                                   'XobsXOS0.txt','XobsXOS1.txt','XobsXOS2.txt','XobsXOS3.txt','XobsXOS4.txt',  &
                                   'XobsXOS5.txt','XobsXOS6.txt','XobsXOS7.txt','XobsXOS8.txt','XobsXOS9.txt'/),  &
                                   SHAPE=(/max_xoms,2/))

otherwise move

filename = RESHAPE(SOURCE=(/'XobsXOM0.txt','XobsXOM1.txt','XobsXOM2.txt','XobsXOM3.txt','XobsXOM4.txt',  &
                                   'XobsXOM5.txt','XobsXOM6.txt','XobsXOM7.txt','XobsXOM8.txt','XobsXOM9.txt',  &
                                   'XobsXOS0.txt','XobsXOS1.txt','XobsXOS2.txt','XobsXOS3.txt','XobsXOS4.txt',  &
                                   'XobsXOS5.txt','XobsXOS6.txt','XobsXOS7.txt','XobsXOS8.txt','XobsXOS9.txt'/),  &
                                   SHAPE=(/max_xoms,2/))

to the position of a first executable statement.

Generally, avoid DATA in Fortran 90 and later.
