VEC_$IASUM                        Domain/OS                         VEC_$IASUM


NAME
     vec_$iasum - sum the absolute value of the elements of a 32-bit integer
     vector

SYNOPSIS (C)
     #include <apollo/base.h>
     #include <apollo/vec.h>

     long int vec_$iasum(
          long int *vector,
          long int &length)

SYNOPSIS (Pascal)
     %include '/sys/ins/base.ins.pas';
     %include '/sys/ins/vec.ins.pas';

     function vec_$iasum(
          in vector: univ vec_$integer32_vector;
          in length: integer32): integer32;

SYNOPSIS (FORTRAN)
     %include '/sys/ins/base.ins.ftn'
     %include '/sys/ins/vec.ins.ftn'

           parameter (nvec = 10)

           integer*4 vector(nvec), sum
           integer*4 length

           sum = vec_$iasum(vector, length)

DESCRIPTION
     Vec_$iasum adds together the absolute value of length elements of the
     32-bit integer array vector and returns the sum.

     vector
          The vector to be summed.

     length
          The number of elements to be operated on;  normally the same as the
          number of elements in the vector.

NOTES
     When vec_$iasum is used to operate on matrixes in C and Pascal, vector is
     a row vector; in FORTRAN, it is a column vector.
