replace Function

private elemental function replace(self, old, new, count) result(replaced)

Return a string with all occurrences of substring old replaced by new.

 type(string) :: astring
 logical      :: test_passed(3)
 astring = 'When YOU are sad YOU should think to me :-)'
 test_passed(1) = (astring%replace(old='YOU', new='THEY')//''=='When THEY are sad THEY should think to me :-)')
 test_passed(2) = (astring%replace(old='YOU', new='THEY', count=1)//''=='When THEY are sad YOU should think to me :-)')
 astring = repeat(new_line('a')//'abcd', 20)
 astring = astring%replace(old=new_line('a'), new='|cr|')
 astring = astring%replace(old='|cr|', new=new_line('a')//'    ')
 test_passed(3) = (astring//''==repeat(new_line('a')//'    '//'abcd', 20))
 print '(L1)', all(test_passed)
