Problem with batch "set" command

Question

Good afternoon. I was doing a very simple programming, in general, serves simply to put the numbers that the user put (10 numbers) in ascending order, but something strange happens already in this part

set /p NM9=
set /p NM10=

:CICLO
if %NM10% EQU %NM9% (
    goto IGUAL1
)
if %NM10% LEQ %NM9% (
    set /a VAR=%NM9%
    set /a NM9=%NM10%
    set /a NM10=%VAR%
)

After giving an echo at the beginning of the cycle, it says that the NM9 and NM10 values are "1". Can you find the problem? I suspect it is the "VAR" part, or maybe some problem in the assembly of the lines. Thank you.

echo %NM1% %NM2% %NM3% %NM4% %NM5% %NM6% %NM7% %NM8% %NM9% %NM10%
pause

The whole code.

Answer 2

The problem is that you are trying to do value assignment and sum within an argument of a command that uses parentheses, using percentages in the variables, and thus only calls variables outside the parentheses of conditions IF and command FOR

how to solve this?

use this command at the beginning of the code SETLOCAL ENABLEDELAYEDEXPANSION

and change the percentages of the variables you are calling to points exclamation variable means a variable %VAR% will look like this: !VAR!

make the appropriate changes, test the code and comment here if given right, blz?
