The following computation looks at the client’s first, middle, and last names and returns only the first character from each of these variables. When merged together, these characters create the client’s initials:
first( ClientFirstName, 1 ) + first( ClientMiddleName, 1 ) + first( ClientLastName, 1 )
In the following example, the first four characters of a client’s last name are merged with a case number to create a file number.
