Works fine for me with PD KSH 5.2.14 99/07/13.2

What has pdksh not done correctly for you?  I haven't had a
problem with it ever.

Now the question, why don't I use bash since bash does everything
korn shell does and more?  Well, because

	bash does too much
	your linux distro is likely to have lots of
	  customizations for bash which differ from
	  distro to distro
	I want a completely 'pure' environment to start
	  with.  None of this 'alias rm="rm -i"' crap.

That's why I don't use bash.  But having had no problems
with pdksh, I don't see any reason to go out and
compile at&t's version when my distro already comes
with pdksh.
