! Purpose: Open file with information for post processor.
!
! Description: None.
!
! Input: 
!   global              Global pointer
!   fileStatus          Status of file to be opened
!
! Output: 
!   fileExists          Logical flag indicating whether file exists or not
!
! Notes: 
!   1. Need special treatment of file opening because in rflupost the file is
!      opened without knowing whether it exists or not, and need to be able to
!      handle latter case gracefully.
