 FYI,
   Some compilers wait until the end of Working-Storage (and Linkage Section
 if appropriate) to issue a message about "referenced data item is not

 reference is made.  Obviously, this must require either a LONG "look-ahead"
 or a two-pass syntax checker.

If we can stay on the track of associating a line number with every 
diagnostic, then we can eventually constuct an algorithm that makes messages 
show up where we want them. So that they 'appear' in an 'early' part of a 
compile even if not fully detected until a review at the end of some whole 
division.  That needs to be designed into the preprocessors line number 
enumeration scheme, and the diagnostics API from the outset; even if the 
SORT/linked list is not implemented until later.
