And don't forget the boundary condition at the beginning when #TEXT 
is empty. You probably don't want it to start with a comma.

Best to use character varying format for these types of string 
operations. Define a 2A VARYING separator string variable 
initialized to '' at the beginning, then set the separator to ', ' 
after appending each piece.

Regarding the 55 character chunks, I'd build up the whole text 
string first, then split at blanks to produce a set of <=55 
character pieces.
