See variables.txt :-

  One-character variables
  -----------------------

  The following one-character variables are also defined.  However, they
are duplicates of the previous general cases, and are only provided
for backwards compatibility.  They WILL BE removed in a future
release.  They also do NOT permit the use of conditional syntax
(':-'), as described above.


    Variable  Description                 Proper Equivalent
    --------  -----------                 ----------------
     %a       Protocol (SLIP/PPP)         %{Framed-Protocol}
     %c       Callback-Number             %{Callback-Number}
     %d       request day (DD)

[snip]
 
     %C       clientname
     %D       request date (YYYYMMDD)
     %H       request hour
     %L       radlog_dir                  %{config:logdir}
     %M       MTU                         %{Framed-MTU}
     %R       radius_dir                  %{config:raddbdir}
     %S       request timestamp
                in SQL format
     %T       request timestamp
                in database format
     %U       Stripped User name          %{Stripped-User-Name}
     %V       Request-Authenticator
                (Verified/None)
     %Y       request year (YYYY)
     %Z       All request attributes
               except password
               (must have a big buffer)

This is from 1.1.x - I assume the file still exists in version 2.x
