Hi, I apologize if my english is bad, I need some help printing the value of a variable in the code that I show below, I'm using emu8086 and I need that this works in this code example that is the same that comes in the examples of emu8086 (PrinterDemo.asm) with a little of modification that is of what I need to print.

Thanks for your help

I don't see what you are trying to do? Which variable do you want to print the value of.. ?
Try this out, and respond with your results.

mov al,VARIABLENAME
storage db 0, "$"
mov [storage],al
mov ah,9
mov dx,storage
int 21h

That uses DOS vector 21h ("$" = string terminator), replace VARIABLENAME with the variable you are trying to display!

This works in NASM16, I cannot be sure it will work on your assembler.

I think the .model tiny directive for the assembler is missing. You also did NOT use a segment declaration.
As it is just ONE segment in tiny model, one single and simple .CODE is sufficient.
Also for compilation use "tasm file" and "tlink /t file" or "ml /c /AT file.asm" and "link16 /t file.obj"

In general it is better to post declarations at the end after int21h, ah - 4ch, but before- end start
