29* =============

31*> \verbatim
32*>
33*> This subroutine translates from a character string specifying a
34*> transposition operation to the relevant BLAST-specified integer
35*> constant.
36*>
37*> ILATRANS returns an INTEGER. If ILATRANS < 0, then the input is not
38*> a character indicating a transposition operator. Otherwise ILATRANS
39*> returns the constant value corresponding to TRANS.
