   I'm working with a pointer to several arrays of type long.  The pointer is
used as a global.  I can't figure out when and where to declare the sizes of
the various arrays.  I have a structure as follows

    instance {
      long *x;
      long *y;
      long *id;
    } ;

and I know I want to declare the size of the x, y, and id arrays to be MAX_SIZE
which I declare as a macro.  Can someone please tell me how I should indicate
to my program the size of these arrays.  I'm getting desperate.

Jon

p.s. - please speak in simple terms, I don't have much experience programming
