Oracle 19c Import Utility - Windows Exit Codes?

Hello, there seems to be no documentation on what the exit codes on Windows are for the (original) Import Utility (not Data Pump). This link:

Only says what they are for Unix (and not even sure it's an exhaustive list).:

For UNIX, the exit codes are as follows:

EX_SUCC=0

EX_OKWARN=0

EX_FAIL=1

I found this link discussing Import util from Oracle 8i, where the submitter got a different value ("1") for "EX_OKWARN":

And responder seems to indicate that on Windows, the codes are different (guessing at the 2 "EX_OKWARN"s):

EX_SUCC=0
EX_OKWARN=1
EX_OKWARN=2
EX_FAIL=3
EX_FTL=4
