labs()                   Calculate Absolute Value of Long Integer

 #include   <stdlib.h>                   Required for declarations only

 long       labs(n);
 long       n;                           Long integer value

    labs() returns the absolute value of the long integer 'n'.

    Returns:    The absolute value of 'n'.  There is no error return.

  -------------------------------- Example ---------------------------------

    The following statements calculate the absolute values of -150000L,
    0L, and 33333L.

         #include <stdlib.h>      /* Required for declaration only */

         main()
         {
             long x, y, z;

             x = labs(-150000L);  /* x = 150000L */
             y = labs(0L);        /* y =      0L */
             z = labs(33333L);    /* z =  33333L */
         }
