Shouldn't that be dtl(30) using parens rather than brackets?  This is a
lookup, not an array.  I've never heard they were interchangeable on
lookup aliases.

Incidentally, I would personally make sure line 2 has a failure test of:

IF:  not dtl
THEN:  'handle error condition here

There is no "I" in TEAM.
This would be the primary reason I've chosen not to join one.
