File Handling (Obsolescence).

I was trying out the file handling features in abap.

I tried using the 'ws_upload' and 'ws_download' functions.

But there was a window which popped up and said, "function obsolete". I could use the function though.

My question is,

If 'WS_DOWNLOAD' AND 'WS_UPLOAD' are obsolete then what functions do I use now?

We are using SAP v4.7 in our office.

Thanks,

Sreekar Pande.
