It depends on what language you are working in, but essentially:
The whole point is you can read/write memory locations without changing the reference since 
it is a pointer to the data in memory.


DIM pArr AS DWORD
DIM arrBytes(0 to 10) as BYTE
pArr = VARPTR (arrBytes)

1. Use PEEK and POKE 
POKE pArr + 3, 65
will set the value of the 4th byte in the array.

2. Dereference using pointer addressing (which may use an asterisk or other operator 
epending on language)
*pArr[3] = 65. does the same thing.
