hmmm ok, i dont aks why you need that
ok in your SAP-SCRIPT form there is a text element called "ITEM_LINE".
this is beeing called once for every ITEM you print.
in this text element make a external perform.
like:
/E ITEM_LINE
/:  DEFINE &ITEM_COUNT& = ' '
/:  perform calculate_item_count in program YOUR_PROGRAM
/:  changing &ITEM_COUNT&
/:  endperform
your external perform shoulöd then look like:
form calculate_item_count tables in_tab  STRUCTURE itcsy
                                                 out_tab STRUCTURE itcsy.
  statics:  lv_count       type i.
  lv_count = lv_count +1.
  read table out_tab
  with key name = 'ITEM_COUNT'.
  if sy-subrc = 0.
    out_tab-value = lv_count.
    modify out_tab index sy-tabix.
  endif.
endform.
well the variable ITEM_COUNT you defined in your form is now accesible throughout the whole form, and can be printed, like other variables.
i hope i got you right this time
