Usage guidelines
The heap memory comprises fixed-size memory blocks (such as size=16 bytes or size= 64 bytes), to store
necessary data or intermediate variables. When a process starts, the system dynamically allocates the
heap memory to the process as needed. To display heap memory information about a process, use the
display process memory heap command.
Each memory block has an address represented in hexadecimal numbers. To display the address, use
the display process memory heap size command. You can access the memory block through the address.
To display the memory block, use the display process memory heap address command.
