Hmm, on my UnixWare machine
$ ksh -c 'a(){ echo hi; }; a'
hi
$ ksh88 -c 'a(){ echo hi; }; a'
hi
Using the 'set -o emacs' ^V trick Ralf taught me, we see
ksh is Version M-12/28/93e-SCO
ksh88 is Version M-11/16/88h
On my Solaris 10 box with ksh Version M-11/16/88i
$ ksh -c 'a(){ echo hi; }; a'
hi
Even my old OpenLinux 3.1.1 machine running pdksh-5.2.14-6MR gets it right
What version of ksh did you test on?
