DECLARE_and_NODECLARE

 cDEC$ DECLARE
 cDEC$ NODECLARE

 The DECLARE directive generates warnings for variables that have
 been used but have not been declared (like the IMPLICIT NONE
 statement).  The NODECLARE directive (the default) disables these
 warnings.

 The "c" in cDEC$ is one of the following:  a C (or c), !, or *.

 The DECLARE directive is primarily a debugging tool that locates
 variables that have not been properly initialized, or that have
 been defined but never used.   

 For compatibility, !MS$DECLARE and !MS$NODECLARE can be used in
 place of cDEC$ DECLARE and cDEC$ NODECLARE.
