The external env(1) utility will only ever list environment

The IFS variable does not need to be exported as an environment
variable
as it's only ever used by the current shell (and any new shell
would
reset it).
To list all variables in a shell, use the built-in set utility
without
any arguments.
$ (unset -v IFS; ksh -c 'set' | grep -A 1 IFS)
IFS='
'
$ (unset -v IFS; ksh -c 'printf "%s" "$IFS" | hexdump -C')
