Packing Commas in a Quiz - but not too many

[Max Buten]

The college likes to address its designees as John Jones, CLU, ChFC, RHU
- 
if Mr Jones has those designations.  I'm having trouble getting the
right number of commas.  The Quiz code I'm using (on HP3000 in version
7.09)
is this:

DEF CLU  CHA*04 = "CLU " if he's earned a CLU
DEF CHFC CHA*04 = "ChFC" if he's earned that one
DEF RHU  CHA*04 = "RHU " if he's earned it
DEF FULL-NAME CHA*40 = PACK("John Jones" + ", " + CLU + ", " + CHFC + ",
" + RHU)

This works fine for somebody with CLU.  However if Jones only has RHU, I
get 

John Jones,,, RHU

which is pretty ugly.  

John Jones, RHU    would be much better.

Surely, somebody has faced and solved this problem?
