Fortran doubly linked list

[tensity]

I am creating a doubly linked list in fortran. Pretty much everything is working correctly. Although, I am having one issue... I build the list properly, but when printed to the screen, I get jumble for the first and last lines. Here is my code

        DO WHILE (.NOT. quit .AND. inStat .EQ. 0)
            ALLOCATE(cur)                                !create a new node
            NULLIFY(cur%prev,cur%next)                   !nullify the pointers
            IF (.NOT. ASSOCIATED(head)) THEN
                !start a new doubly linked list
                ALLOCATE(head)                           !create a head
                NULLIFY(head%prev,head%next)             !nullify head's pointers
                ALLOCATE(tail)                           !create a tail
                NULLIFY(tail%prev,tail%next)             !nullify tail's pointers
                head => cur                              !point head to cur
                READ(1,*,IOSTAT=inStat)cur%name          !store name in cur
                READ(1,*,IOSTAT=inStat)cur%cnt           !store count in cur
            ELSE
                cur%prev => tail                         !point cur's prev to the previous tail
                tail%next => cur                         !point tail's next to cur
                READ(1,*,IOSTAT=inStat)cur%name          !store name in cur
                READ(1,*,IOSTAT=inStat)cur%cnt           !store cnt in cur
            END IF
            tail => cur                                  !point tail to cur
        END DO
        cur => head                                      !point cur to head
        DO WHILE (ASSOCIATED(cur))                       !while there is more
            PRINT *,cur%name, ' ', cur%cnt
            cur => cur%next
        END DO

The input file contains the following:
nick
7
jim
5
mike
16
rob
15
steven
16
johnathan
-5

What is printed:

 J↓K l■(     ─ ( e┬æuƒ          704

I've changed the code around a bit and fixed a few things and now I am getting the correct output. One problem, though, is that initially the program is not entering the IF(.NOT. Associated(head)) THEN structure.

      TYPE (node), POINTER      :: head, cur, tail      !pointers to the data
      TYPE (node), TARGET       :: new
      INTEGER                   :: cntTemp              !for data verification while importing from file
