  26 ALSO :
  27  this script use an $op to know what to do.
  28  if $op is empty or none of the above values,
  29     - the default screen is build (with all records, or filtered datas).
  30     - the   user can clic on add, modify or delete record.
  31  if $op=add_form
  32     - if primkey exists, this is a modification,so we read the $primkey record
  33     - builds the add/modify form
  34  if $op=add_validate
  35     - the user has just send datas, so we create/modify the record
  36  if $op=delete_form
  37     - we show the record having primkey=$primkey and ask for deletion validation form
  38  if $op=delete_confirm
  39     - we delete the record having primkey=$primkey
