Turning Anynet on/off OK?

If I CHGNETA ALWANYNET(*YES) and then IPL and do some testing (to see if some 
code still works with Anynet turned on), can I simply CHGNETA ALWANYNET(*NO) 
and IPL again to put everything back the way it was before? i.e. will turning 
Anynet support on make any permanent changes to any comm (or other) objects 
that turning Anynet back off will not "undo"?

Also, I wasn't actually planning to create the config objects to use Anynet 
with another machine. I was just going to turn it on/off. Do you think my test 
would be valid this way, without Anynet actually being used? (the code being 
tested is TCP/IP-only, no SNA - I don't think the presence of Anynet "should" 
mess it up, but sometimes we don't know for sure until we try)

Thanks,
