IMSL Name:  SASUM (Single precision version)
 
Revised:    August 9, 1986
 
Purpose:    Sum the absolute values of the components of a
            single precision vector.
 
Usage:      SASUM(N, SX, INCX)
 
Arguments:
   N      - Length of vectors X.  (Input)
   SX     - Real vector of length N*INCX.  (Input)
   INCX   - Displacement between elements of SX.  (Input)
            X(I) is defined to be SX(1+(I-1)*INCX). INCX must be
            greater than 0.
   SASUM  - Single precision sum from I=1 to N of ABS(X(I)).
            (Output)
            X(I) refers to a specific element of SX.
