Purpose:

!>
!> This subroutine translates from a character string specifying a
!> transposition operation to the relevant BLAST-specified integer
!> constant.
!>
!> ILATRANS returns an INTEGER.  If ILATRANS < 0, then the input is not
!> a character indicating a transposition operator.  Otherwise ILATRANS
!> returns the constant value corresponding to TRANS.
