jump to label?

[j00n]

Code Select Expand

include \masm32\include\masm32rt.inc

.data

   num1 sdword 5
   
.data?

.const

.code

start:

    main proc

    mov eax, 3             
    cmp num1, eax               ;5 - 3    compare 5 and 3
    je eqqq                     ;jump over(not equal) to eqqq
    print "not equal", 0Ah      ;else print not equal
eqqq: print "equal", 0Ah
    inkey                       ;wait for input

    ret
 
    main endp

end start



I can't get around this problem i'm having where both labels are printed when I only need one or the other...

is there a way to make a label only appear when called?

like this

error1: print "error1"
error2: print "error2"

these only show when I jump to them?

    jne neqq                    ;jump if not equal to label neqq

eqqq: print "equal", 0Ah
jmp @fin
neqq: print "not equal", 0Ah
jmp @fin

    @fin:

    inkey "Press any key to exit"

    ret
    main endp
   
end start

like this

error1: print "error1"
error2: print "error2"

No.
You must declare a second label:

Code Select Expand

error1: print "error1"
jmp @fin
error2: print "error2"
jmp @fin
[....]
@fin:
Also you can use MASM .if/.elseif/.else/.endif Constructs or MASM32's switch-macros.

Code Select Expand

   je eqqq                     ;jump over(not equal) to eqqq

   print ("not equal"),0Dh,0Ah ;else print not equal
   jmp  done

eqqq: print ("equal"),0Dh,0Ah

done:
   inkey                       ;wait for input

in this case, you could "share" part of the string....

Code Select Expand

   je eqqq                     ;jump over(not equal) to eqqq

   print ("not ")              ;else print not equal

eqqq: print ("equal"),0Dh,0Ah
   inkey                       ;wait for input

is that what you mean ?

Thanks for your help, I updated my post with the final code.

eqqq: print "equal", 0Ah
jmp @fin
neqq: print "not equal", 0Ah
jmp @fin                                ;you may omit this JMP

    @fin:
