undocumented commands

A well-written command will respond to:

   command_name -?
or
   command_name /?

Try it!

The only thing these flags did, when executing arcinst, is add new archives to os2/archives. I had tried the "?" without the "-" or "/" before with the same results.

Please be specific -- which .EXE or .COM or .CMD file do you consider to be "undocumented",
and why do you think that executing it will be to your advantage?

In my os/2 user group one person was having problem with his desk top one response from another user was to use the arcinst command to archive your current desk top instead of setting the archive flag and have to remember to remove when you start your system. This and a lot of other exe and cmd are in the x:\os2 directory, but with no available documentation that I can find. As my question states I am not looking for documentation on one command but documentation on the commands available in the above directory. Also I can not say if executing them is to my advantage until I know what they do!!!

Well, given the list of files in the OS2 directory, some are REXX files,
which you can "inspect":

HELP.CMD
PATCHWP.CMD
REXXTRY.CMD
SETVGA.CMD
SRD2FIX.CMD

Others are documented commands (enter "HELP _name_"):

BOOT.COM
CHKDSK.COM
COMP.COM
DISKCOMP.COM
DISKCOPY.COM
FDISK.COM
FORMAT.COM
KEYB.COM
LABEL.COM
MODE.COM
MORE.COM
PRINT.COM
RECOVER.COM
TREE.COM
UNDELETE.COM

Which ones intrigue you?

Well its nice to know what they are. My question was what do they do?

Open an OS/2 window, and enter 'help FILENAME',
where "FILENAME" is any one of the above names.
Which one(s) returns "topic not found" ???

Rather than duplicating the IBM documentation in my reply,
let's restrict our discussion to the "undocumented" ones.

Lets limited to arcinst command. Help arinst results in no topic found. Where do I find additional information on this command?
