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.
