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.
