Depends on the platform you're compiling for, the type of access required
and the operating system the program will run on.
For the go32v2 - target, read the go32 unit documentation about accessing
DOS memory, this might help.
For the others it depends highly on the operating system (as it is with
DOS/go32) and the API calls offered - but generally speaking the answer is
"no" without special preparations and/or knowledge of OS internals (this is
not the fault of the compiler ;-).
If you do extensive manipulation, and limit yourselves to the DOS platform I
recommend using a native 16 bit compiler just because FPC programs introduce
lots of unnecessary overhead. Iirc Borland gives away its TP/BP7(?) for
... another 2 cents ...
