POSIX requires in some cases that it not be Bourne. POSIX shell requires
tilde expansion, absent in Bourne shell.
POSIX requires that system() invoke a POSIX shell. Bash may deviate.
I don't know that POSIX discusses a "default shell".
BTW:
534 $ X=Out; { X=In; true; } </dev/null; echo $X
In
... seems POSIXly correct to me. I've known one "Bourne" shell that
prints "Out".

One for the "too hard basket" then Jerry?! It would be fantastic to have
bash as the default shell for z/OS but that
ain't gonna happen anytime soon :)
