Dereferencing pointers is different from modifying the code in that it
frees up your stack/registers.

Dereferencing pointers:

0000A0BF: jmp *%ecx

to change which function you execute you change ecx

Modifying code with jmps:
0000A0BF: jmp 0x0000BD00

to change which function you execute you write to the place in memory
that holds the number 0x0000BD00

Modifying code with function copying:

0000A0BF: nop
...
0000D0BF: nop

to change which function you execute you write the function code to
the place in memory that holds the nop's.
