Question on assembly code

[yzou_ua]

Would someone pls let me know the meaning of following code?? Is it just for distribution of values to variables?? Buz obviously 'Estim_a' to 'f' are variables used in main code. Then why the numbers are 0, 2,4,6, etc.

.......

.equ Estim_a, 0 ;
.equ Estim_b, 2 ;
.equ Estim_c, 4 ;
.equ Estim_d, 6 ;
.equ Estim_e, 8 ;
.equ Estim_f, 10 ;

.......

I know too little about assembly code, so thx for patient explanation.

.equ Estim_a, 0 ;

means whereever the symbol 'Estim_a' appears in the code
replace by '0'.

Estim_b by 2 etc...

it is a short form for writing constants in assembly codes.

Thx.
Then, why the numbers are 0,2,4,6,8 etc. ?? I mean why they are just even number series?? Maybe this is not a good question, but I thought look like addr. or sth...

.equ Estim_a, 0 ;

means whereever the symbol 'Estim_a' appears in the code
replace by '0'.

Estim_b by 2 etc...

it is a short form for writing constants in assembly codes.

why it is even numbers only ?
well that depends on what the code is written for .

no other reason .

You can share your code to help you understand it.
