"Any" pointer data type

The pointer data type ANY ("Any") points to the beginning of a data area and specifies its
length. The ANY pointer uses 10 bytes in memory and can include the following information:
● Data type: Data type of the data elements
● Repeat factor: Number of data elements
● DB Number: Data block in which data elements are stored
● Storage area: Memory area of the CPU, in which the data elements are stored
● Start address: "Byte.Bit" starting address of the data
The following image shows the structure of the ANY pointer:
A pointer can not detect ANY structures. It can only be assigned to local variables.
