  23  this script use an $op to know what to do.
  24  if $op is empty or none of the values listed below,
  25         - the default screen is built (with all or filtered (if search string is set) records).
  26         - the   user can click on add, modify or delete record.
  27     - filtering is done on the code field
  28  if $op=add_form
  29         - if primary key (module + code) exists, this is a modification,so we read the required record
  30         - builds the add/modify form
  31  if $op=add_validate
  32         - the user has just send data, so we create/modify the record
  33  if $op=delete_form
  34         - we show the record selected and ask for confirmation
  35  if $op=delete_confirm
  36         - we delete the designated record
