Bzzz. Nope, sorry, wrong answer. This will work on a .COM file only.
In any other memory model, ie, one which creates a .EXE file, there can
be uninitialized data such as empty arrays, etc which are defined in size
but not stored in the .EXE file. I don't know a sure-fire way to determine
the size of a program, but filelength on an EXE will almost always be wrong.

There are some documented and undocumented internal variables, such as
_heapbase, _heaplen, etc, which may point you in the right direction. You
may also want to consider using the keep() function which calls DOS
function 31 to TSR >64K ....

Hope this helps ...
Steve
