   31: *> \verbatim
   32: *>
   33: *> This subroutine translated from a character string specifying an
   34: *> intermediate precision to the relevant BLAST-specified integer
   35: *> constant.
   36: *>
   37: *> ILAPREC returns an INTEGER.  If ILAPREC < 0, then the input is not a
   38: *> character indicating a supported intermediate precision.  Otherwise
   39: *> ILAPREC returns the constant value corresponding to PREC.
