void freeze(bool freezefl = true);
Effects: If strmode & dynamic is nonzero, alters the freeze status of the dynamic array object as follows:
If freezefl is true, the function sets frozen in strmode.
Otherwise, it clears frozen in strmode.
char* str();
Effects: Calls freeze(), then returns the beginning pointer for the input sequence, gbeg.
Remarks: The return value can be a null pointer.
int pcount() const;
Effects: If the next pointer for the output sequence, pnext, is a null pointer, returns zero. Otherwise, returns the current effective length of the array object as the next pointer minus the beginning pointer for the output sequence, pnext - pbeg.
