Variable output

[Timofeyka]

Hello.
I need help - I don't know how to print a variable through normal print, without masmBasic and kip irvines library. Who knows, tell me.

print str$(myvar), 13, 10

[Timofeyka]

lol

[Timofeyka]

print str$(myvar), 13, 10

My code with this is not working
  ^{.686
  .model flat, stdcall
  option casemap :none
  include C:\masm32\include\masm32rt.inc
  .data
    s db "SS",0
  .code
  main:
    print str$(s)
  end main}

include \masm32\include\masm32rt.inc

.data
myvar dd 12345

.code
start:
  print str$(myvar), " is the value of myvar", 13, 10
  inkey "press any key"
  exit

end start

- use include \Masm32\include\..., not C:\Masm32; many members use other drives

no errors, but no output

- did you use "console assembly"?
- was an exe file created?
- did you see any error messages?

1. Yes(Subsystem in Link).
2. Yes.
3. No.
I have now specially compiled and linked manually.

How many bytes does your executable have?
What exactly do you see when you run the exe from a DOS prompt?

The only reason I could imagine that you don't see anything would be an AV that silently blocks the exe.

The size is 2.50 kilobytes. I run the file from the console, half a second passes, and the program closes.

Size is ok. Mysterious - please zip the exe and attach it to a post here.

Ok

Thanks. You are victim of a very old MASM bug:

Use UAsm.

[hutch--]

You may need to add that you don't normally PUSH a 16 bit register in 32 bit as an argument. He probably needs UASM where MASM requires correct code.

[jj2007]

Hutch,

This is the code that I proposed, and that he apparently used. No idea where the push ax comes from
