8.4.3 Valid_State_Logical Procedure

The Valid_State_Logical procedure returns true iff the logical scalar or array variable is in a valid state - that is, iff the variable passes all of the valid state tests.

Calling syntax:

Logical = Valid_State(L)	or
Logical = Valid_State_NP(L)

Input variable:

L

A logical scalar variable or a pointer to an allocated logical array variable. A non-pointered variable may be used with the Valid_State_NP version of the call.

Output variable:

Valid_State

True iff the logical scalar or array variable is in a valid state.

The Valid_State_Logical code listing contains additional documentation.
