You can look forward to being neither surprised nor delighted.

From Managing Catalogs, SC23-6853-02, page 19: 

"The symbolic string must not exceed 44 characters, including all name segments 
and periods."

Does that restrict the length of related DSNs to 39 characters rather than 44 
because a 5-character name is replaced by a 0-character value?  Of course a 
thoughtful design would allow the SYMBOLICRELATEd DSN to be comfortably longer 
then 44 characters because symbol resolution may reduce that length.
Somehow I don't trust IBM designers to have been so thoughtful.  For example, 
ISPF DSLIST restricts the name entered to be at most 44 characters regardless.
I'd be delighted to be surprised.
