Confirmed..

A clean exit from the posix shell sets CJCW = 0

:showjcw cjcw
CJCW=0

:sh -L
shell/ix>uisaouf
uisaouf: not found
exit
:showjcw cjcw
CJCW=127

:sh _L
shell/ix>exit
:showjcw cjcw
CJCW=0


Timing is everything. I am currently working with the posix shell in a batch
job and needed this! Thanks Carl.

Now, anyone know where to find the list of codes?
