> I would appreciate a response from each of you (whether you use JPI M2

MODULE t;
PROCEDURE f () : INTEGER;
BEGIN END f;
VAR a : INTEGER;
BEGIN
a := f()
END t.
JPI 1.17 - compile time error
FST, Logitech 3.03, JPI 2.0, QuickMod, FTL - no compile time error
QM and FTL did not even report run time error.
While a preference would be for a compile time error, note that the presence
of a RETURN does not mean you cannot switch off run time checking, unless you
are very clever. For example, the code below would not execute the RETURN.
MODULE t;
PROCEDURE f () : INTEGER;
BEGIN
IF FALSE THEN RETURN 1 ELSE END
END f;
VAR a : INTEGER;
BEGIN
a := f()
END t.
