Fortran 90's ALLOCATE and DEALLOCATE is not supported by g77. g77 does
do automatic arrays.
An automatic array is an array (in a subprogram) that gets its size from
a dummy argument of the subprogram, e.g.:
SUBROUTINE SUB(A,N)
DIMENSION A(N), B(N)
...
END
Here A is a normal, dummy argument array, whereas B is an automatic
array that is allocated everytime control enters the subroutine SUB.
Hope this helps,
