This entry comes as this file, SQL.PRE, plus the compiler,
SQLCOMPILER.PL. I haven't had time to test it. The top-level predicate
is translate/3 - see the comments in the code.


CHECKED ON EDINBURGH-COMPATIBLE (POPLOG) PROLOG : no.


PORTABILITY : looks pretty good, but I haven't checked it. This kind of
program shouldn't have many problems. Look out for the type-checking
predicates, right at the end.                  


INTERNAL DOCUMENTATION : Predicates are commented with a brief statement
of their purpose. The comments mention a report, obtainable from the
author.
