Sorry, sent it out without finishing.  The worst is "return".
With ksh, ash, and dash, the script itself exits with status
code 1 (presumably you are trapping it with trap -- exit,
though).

prompt$ bash k.sh exit
foo
prompt$ bash k.sh false
foo
status 1
prompt$ bash k.sh return
foo
k.sh: line 20: return: can only `return' from a function or sourced script
status 1
prompt$ ash k.sh exit
foo
prompt$ ash k.sh false
foo
status 1
prompt$ ash k.sh return
foo
prompt$ ksh k.sh exit
foo
prompt$ ksh k.sh false
foo
status 1
prompt$ ksh k.sh return
foo
