I guess there are lots of ksh funs here ;-)

Could you please show me ksh's analog to bash's PIPESTATUS
internal variable. I use this variable in PS1 prompt like this.

0 ~>true | false
0 1 ~>false | true
1 0 ~>false | true
1 0 ~>true | true
0 0 ~>

I just cannot live without this feature.

Another question is whether zsh has the same ability.

More global question is why there is _easy_ way to obtain
pipe status in standard /bin/sh but this is offtop here I thinks :(
