Specifying the application ID

The name of the application, the date to which it is valid, and the status uniquely identify each application. The application ID can be from 1 to 16 characters, the first of which must be either an alphabetic or national character. All other characters must be alphanumeric. For example, these are valid application IDs:
     MYAPPLICATION£1, §MYAPPL, A
while these are invalid application IDs;
     MYAPPLICATION*1, 1MYAPPL, &
