	   SLAMC3

Function/Subroutine Documentation
   REAL function slamc3 (realA, realB)
       SLAMC3 Purpose:

	SLAMC3	is intended to force  A  and  B  to be stored prior to doing
	the addition of  A  and  B ,  for use in situations where optimizers
	might hold one of these in a register.

   REAL function slamch (characterCMACH)
       SLAMCH Purpose:

	    SLAMCH determines single precision machine parameters.

       Parameters:
	   CMACH

		     Specifies the value to be returned by SLAMCH:
		     = 'E' or 'e',   SLAMCH := eps
		     = 'S' or 's ,   SLAMCH := sfmin
		     = 'B' or 'b',   SLAMCH := base
		     = 'P' or 'p',   SLAMCH := eps*base
		     = 'N' or 'n',   SLAMCH := t
		     = 'R' or 'r',   SLAMCH := rnd
		     = 'M' or 'm',   SLAMCH := emin
		     = 'U' or 'u',   SLAMCH := rmin
		     = 'L' or 'l',   SLAMCH := emax
		     = 'O' or 'o',   SLAMCH := rmax
		     where
		     eps   = relative machine precision
		     sfmin = safe minimum, such that 1/sfmin does not overflow
		     base  = base of the machine
		     prec  = eps*base
		     t	   = number of (base) digits in the mantissa
		     rnd   = 1.0 when rounding occurs in addition, 0.0 otherwise
		     emin  = minimum exponent before (gradual) underflow
		     rmin  = underflow threshold - base**(emin-1)
		     emax  = largest exponent before overflow
		     rmax  = overflow threshold  - (base**emax)*(1-eps)
