Re: Bytes Swapping in iSeries

[srilaxmi@xxxxxxx]

Hi Scott,

I understood what you are saying. My problem is the third party(PC) they do
not want to do the bytes swapping, so my end (On AS/400) need to do the
swapping and send.Is there any other way to do the bytes swapping on
AS/400.

Thanks
Lakshmi

I already explained this to you off-list, but I'll explain it again here:

   htons converts from host byte-order to network byte-order.
   ntohs converts from network to host.

The byte order used by the iSeries is the SAME as the byte order used by
the network -- therefore htons and ntohs are NO-OPs.  They do nothing.

It's the PC that uses a different byte order from the network.  It's the
PC program that needs to call htons, not your RPG program.
