how in assembly masm do if not less statement

i have code in vb.net

 if not variable1 < variable2                 count += 1             end if  if not variable1 < variable3                 count += 1             end if  msgbox.show(count)

for code count = 1

i tried below code , not work. either gives me count = 2 @ end or count = 0 @ end. should give me count = 1

here code assembly masm

.data  variable1        dd ? variable2       dd ? variable3       dd ?

this suppose happen. read text file 3 values 500,109,500 stored 3 variables so

variable1 = 500 variable2 = 109 variable3 = 506

then need list these in order least greatest tried compare these.

i tried of these variations , none of them worked

    mov esi, offset variable1     mov ecx, offset variable2      .if esi > ecx     inc count     .endif   mov ecx, offset variable3  .if esi > ecx     inc count     .endif 
    .if variable1 > offset variable2         inc count         .endif  .if variable1 > offset variable3         inc count         .endif 
 mov esi, offset variable1         mov ecx, offset variable2      cmp esi,ecx     jb n2     inc count     n2:  mov ecx, offset variable3      cmp esi,ecx     jb n3     inc count     n3: 
    mov esi, offset variable1         mov ecx, offset variable2      cmp esi,ecx     jg n3     inc count     n3:  mov ecx, offset variable3      cmp esi,ecx     jg n4     inc count     n4: 
mov esi, [variable1] mov ecx, [variable2] cmp esi, ecx ja n1 inc level3dns1rank n1:  mov ecx, [variable3] cmp esi, ecx ja n2 inc level3dns1rank n2:

how can convert above vb.net code masm assembly

thank you

update

here answer these 2 questions

what needed convert string integer. used code invoke atodw,addr variable1 if not in assembly changed if not variable1 < variable2 if variable1 > variable2

perhaps:

mov esi, [variable1] mov ecx, [variable2] cmp esi, ecx jge n2

update

aha. see problem now. have:

variable1        db "500",0 variable2       db "109",0 variable3       db "506",0

that gets stored in memory (the hex bytes):

variable1  35 30 30 00 variable2  31 30 39 00 variable3  35 30 36 00

but when load register memory, loads little-endian. when have:

mov esi, [variable1] mov ecx, [variable2]

the contents of esi 00303035, , ecx 00393031. , last value loaded 00363035.

you're trying load string of characters unsigned 32-bit value. wanting compare strings?

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
