  29  <P> As described above vertical positions are specified as a numeric
  30   value [0..n] where 'n' is an arbitrary constant. (For practical
  31   purposes n is most likely &lt; 100)</P>
  32  <P> Using our previous example we will illustrate this parameter by
  33   changing the position of our 'Project' activity to position 7. Therefor
  34   we change the call to GanttBar() to<DIV class="phpscript"><CODE><FONT color="#000000">
