ksh88 or ksh93

Hi all!
Does anybody know how can I check if any UNIX installation has implemented ksh88 or ksh93?
Thanks in advance.

If the following command raises an error, you have ksh88 (or pdksh or mksh, in the last two implementations there is a variable KSH_VERSION), otherwise you have ksh93:

print ${.sh.version}

You can check the exact version by pressing Cntrl-V in command mode:

set -o vi
# press Escape
# press Cntrl-V
