SYNOPSIS

use M_anything, only : empty, assignment(=)

DESCRIPTION

A convenience routine that sets an array to an empty set.

EXAMPLE

Sample program:

   program demo_empty_
   use M_anything, only : empty, assignment(=)
   integer, allocatable      :: ints(:)
   character(:), allocatable :: strs(:)
   real, allocatable      :: reals(:)
      ints=empty
      write(*,*)size(ints)

      write(*,*)’give them some size ...’
      reals = [1.0,2.0,3.0]
      ints = [1,2,3]
      strs = [character(len=10) :: "one","two","three","four"]
      write(*,*)size(ints)
      write(*,*)size(reals)
      write(*,*)size(strs)

      ints=empty
      reals=empty
      strs=empty
      write(*,*)’back to empty ...’
      write(*,*)size(ints)
      write(*,*)size(reals)
      write(*,*)size(strs)

   end program demo_empty_

Expected output:

   >             0
   >   give them some size ...
   >             3
   >             3
   >             4
   >   back to empty ...
   >             0
   >             0
   >             0
