- * VAR_SCALAR - 1 means this is a scalar variable and not

- * to the variable's value, a Tcl object.
- * VAR_ARRAY - 1 means this is an array variable rather
- * than a scalar variable or link. The
- * "tablePtr" field points to the array's
- * hashtable for its elements.
- * VAR_LINK - 1 means this Var structure contains a
- * pointer to another Var structure that
- * either has the real value or is itself
- * another VAR_LINK pointer. Variables like
- * this come about through "upvar" and "global"
- * commands, or through references to variables
- * in enclosing namespaces.
- * VAR_UNDEFINED - 1 means that the variable is in the process
- * of being deleted. An undefined variable
- * logically does not exist and survives only
- * while it has a trace, or if it is a global
- * variable currently being used by some
- * procedure.
- * VAR_IN_HASHTABLE - 1 means this variable is in a hashtable and
- * the Var structure is malloced. 0 if it is
- * a local variable that was assigned a slot
- * in a procedure frame by the compiler so the
- * Var storage is part of the call frame.
- * VAR_TRACE_ACTIVE - 1 means that trace processing is currently
- * underway for a read or write access, so
- * new read or write accesses should not cause
- * trace procedures to be called and the
- * variable can't be deleted.
- * VAR_ARRAY_ELEMENT - 1 means that this variable is an array
- * element, so it is not legal for it to be
- * an array itself (the VAR_ARRAY flag had
- * better not be set).
- * VAR_NAMESPACE_VAR - 1 means that this variable was declared
- * as a namespace variable. This flag ensures
- * it persists until its namespace is
- * destroyed or until the variable is unset;
- * it will persist even if it has not been
- * initialized and is marked undefined.
- * The variable's refCount is incremented to
- * reflect the "reference" from its namespace.
- *
- * The following additional flags are used with the CompiledLocal type
- * defined below:
- *
- * VAR_ARGUMENT - 1 means that this variable holds a procedure
- * argument.
- * VAR_TEMPORARY - 1 if the local variable is an anonymous
- * temporary variable. Temporaries have a NULL
- * name.
- * VAR_RESOLVED - 1 if name resolution has been done for this
- * variable.
