Pointer
Use
This reserved word represents the null pointer value used in numerous pointer operations.
It is also used to check:
- if a REF_CLASS-type variable is instantiated or to remove the reference from a class instance held by a REF_CLASS-type variable.
- if an IMAGE-type variable is empty or to empty an IMAGE-type variable by assignment.
Example
WPTR = *NULL
IF MyCarClass = *NULL
END
MyCarClass = *NULL
ZIMAGE = *NULL
IF ZIMAGE = *NULL
END
