# DECLARE and NODECLARE

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

!DIR$ DECLARE

!DIR$ NODECLARE

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.
