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.
