Extraction from a list

Question

hi all.
we have a requirement that
there is a FILE having no's separated by commas( Ex: file contents are 402,80-,567-,666,942-,.....(n rows and r colomns)) where the negative sign appears at the end rather than at the front.
we want that to be at the front.
for that we have found one FM named  'CLOI_PUT_SIGN_IN_FRONT' which changes the negative sign in front.but for this i need to extract each and every number from the above mentioned file contents to be inputted into this FM.
any ideas how to implement this FM for  the above FILE ????

Answer 1

hi pankaj,the problem is how to extract each particular no. from the FILE i mentioned so as to input it to the FM.
actuall the FILE is like
loop at itab2
              itab2-sales_doc
              itab2-sales_itm
              itab2-prod_date
              itab2-ship_date
              l_revenue
              l_mat_pla
              l_mat_act
              l_mat_var
              l_lab_pla
              l_lab_act
              l_lab_var
              l_bur_pla
              l_bur_act
              l_bur_var
              l_tot_cost_pla
              l_tot_cost_act
              l_tot_cost_var
              l_prm_var
endloop.
where each variable has some value changing after the loop.
now i have to input each and every variable into this FM.........
any ideas???????????
