8.5.3 Valid_State_Character Procedure

The Valid_State_Character procedure returns true iff the character 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(C) or
Logical = Valid_State_NP(C)  

Input variable:

 C  A character scalar variable or a pointer to an allocated character 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 character scalar or array variable is in a valid state.

The Valid_State_Character code listing contains additional documentation.
