Usage guidelines
Heap memory comprises fixed-sized blocks such as 16-byte or 64-byte blocks. It stores data and
variables used by the user process. When a user process starts, the system dynamically allocates heap
memory to the process.
Each memory block has an address represented in hexadecimal format, which can be used to access the
memory block. You can view memory block addresses by using the display process memory heap size
command, and view memory block contents by using the display process memory heap address
command.
