The user profile name identifies the user to the server. This user
profile name is also known as the user ID. It is the name that the user types
in the User prompt on the Signon display.
The user profile name can be a maximum of 10 characters. The characters
can be:
- Any letter (A through Z)
- Any number (0 through 9)
- In addition to these characters, three special codepoints
are allowed (x'5B', x'7B', x'7C'). For many CCSIDs, including 37, these code
points are interpreted as $, #, and @. For other CCSIDs, however, these code
points represent other characters. Although these code points are allowed,
you should avoid using them because of the potential misinterpretation when
multiple CCSIDs are used on a single system. For example, a Spanish-speaking
person using CCSID 284 might create a user profile with the name ESPA OL, but an English-speaking
person using CCSID 37 might see this name as ESPA#OL.
The user profile name cannot begin with a number.
Note: You can create a user profile such that when a user
signs on, the user ID is only numerals. To create a profile like this, specify
a Q as the first character, such as Q12345. A user can then sign on by entering
12345 or Q12345 for the User prompt on the Signon
display.
