In my procs, i use very often local or global variable and lebels like i,j,k,l..., but i cannot define like anonymous. I solve the problem as defined it as i1,i2..., but my procs is too much and compiler often return me error message "symbol already defined". Is it possible to define anonymous variables and how?

Thanks in advance

Did you mean:
Code:
data:
Variable_array dd 0,0,0,0,0,0,0,0,0,0 ;10 variables

code:
mov  eax,[Variable_array]
add  ebx,[Variable_array+4] ;notice the DWORD offset
xor  ecx,[Variable_array+8]
shld eax,ebx,cl
mov [Variable_array+36],eax ;the last in line
    
?
But it doesn't have any error checking so +40 already intrudes another var.
Other examples are *local* variables. You can use them twice, but only in their scope:
Code:
Label1:
    .j:
        ;some code...
    .k:
        ;more code
        jmp .j ;This jumps to Label1.j
Label2:
    .j: ;you can use it here again!
        ;some code...
    .k:
        ;...
        jne .k ;This jumps to Label2.k
        jmp Label1.k ;If you REALLY need to get out of this scope Very Happy

Thanks Madis731 for quick replay. Smile
But simples solve my problems in part (i know about simple 2).
My job is to united part A, B, C... in one part, where first man write part A, second - part B, .....
But one man wrote:
proc ....,arg1,arg2,..
i dd ?
j dd ?
...
enter
...
Second:
proc ....,arg1,arg2,..
i dd ?
n dd ?
enter
....
And i lost a time to edit working procs... Mad
I told - man "A" to write i1,j1 for him variable, and man "B" to write i2, n2....
But it help me almost but not quite and confuse work my colleagues.

You might want to check out "virtual". I don't know if it solves you problem, but if it doesn't I hope someone else on the board can help.

Use local variables as Madis advice and your men won't have any problems.They could decide freely the names for the variables regardless the other's procedures, even in different files and different computers (everyone can build the project accross the network).
Code:
proc ....,arg1,arg2,..
.i dd ? ; variable is local to the proc scope
.j dd ?
...
enter
...
;Second:
proc ....,arg1,arg2,..
.i dd ?
.n dd ?
enter 
;...
