U_NAME() (STRING)

 Function
  Get the current users name.

 Syntax
  U_NAME()   No arguments are required

 Return Type & Value
  STRING
  Returns a string with the current users name.

 Remarks
  Perhaps the most important piece of information about a caller is his
  name.  The user name differentiates a user from every other user on the
  BBS and can be used to track PPE user information that must be kept
  separate from all other users information.  Unlike the predefined U_...
  user variables, this function does not require the use of GETUSER to
  return valid information.

 Examples
  IF (U_NAME() = "JOHN DOE) THEN
    PRINTLN "I know who you are!  Welcome!"
    GETUSER
    LET U_SEC = 110
    PUTUSER
    PRINTLN "Automatically upgraded!"
  ENDIF
