Work File Type SAG

Hi,
with this type of file
is possible to include record, modification and deletion?

Or only with Adabas.

Natural work files are sequential files that can be read from or written to (write option can be APPEND). No record update is possible. It is not a data base file.

TYPE SAG just refers to the format of the work file - look here → [url]http://techcommunity.softwareag.com/ecosystem/documentation/natural/nat6313win/sm/definewo.htm#Work_File_Type_os[/url]

Thanks.
