Character Limitations

Is there a character limitation on the Username field? Password has one, Oener has one, does Username?

See the documentation on ADD Username:

It's a 1-12 alphanumeric characterstring + underscore and $.

Louann,

Kalle give the full answer,
but I am not sure I fully understand the intro to your question.

What do you mean by character limitation on the Owner field?
There is a LENGHT limitation (max 31 chars),
but other than that? ANYTHING printable can be used.
As always in VMS, if you are using lowercase or any special character, just enclose it betwen double quotes. You can even specify a double quote, by entering as a double double quote.

Now, of course, if you are going the retrieve them an use in some programming, you WILL have to take special provisions for spaces, single and double quotes, as well as several others, but that is another issue.
As an example: Dutch names often contain spaces, and single quotes are not very rare.
They are processed just OK.

hth,

Proost.

Have one on me.

Thank you for the information. I guess I should have said, "length limitation" rather than "character limitation."

Have a great day.

The (length) limitations are:
Username 12 positions
Password 32 positions
If you set in SYSUAF the flag for casesensitive, the password is also casesensitive and accepts special characters, otherwise its caseblind and only alphanumeric (no special characters). Username is always case blind.

Note that the username length limit is really 32 characters, but a few things don't work properly if you exceed 12 characters (for example, MAIL). So, AUTHORIZE imposes 12 as an artificial limit. If you access SYSUAF directly, you can exceed 12 characters. Logging in works, as do most other things, but it's not supported.
