I am trying to take 3 variables, and combine them into 1 while using the STRING verb. My items are as follows:

FIRST-NAME PIC X(10).

MIDDLE-INITIAL PIC X(1). LAST-NAME PIC X(20).

FULL-NAME PIC X(31).

What I want out of this is the format of: last, first middle. Example: Doe, John C.

I'm trying to read in a ton of names, not just one single name.
