Shift
Argument-shift and entry-shift are always integer numbers

Argument-Shift = 2
Entry-Shift = 0

Argument	Entry
30	7
40	8
10	9
20	10

Argument-Shift = 0
Entry-Shift = 2

Argument	Entry
10	9

Displacement
Argument-displacement and entry-displacement are the same type of numbers as the value of the table. It might vary from argument and entry.

Argument-Displacement = 2
Entry-Displacement = 0

Argument	Entry
12	7
22	8
32	9
42	10

Argument-Displacement = 0
Entry-Displacement = 3

Argument	Entry
10	10
20	11
30	12
40	13

Argument-Displacement = 2
Entry-Shift = 3

Argument	Entry
12	10
22	7
