Problem with batch "set" command

Navigation
0

Good afternoon. I was doing a very simple programming, in general, simply serves to put the numbers that the user put (10 numbers) in ascending order, however something strange happens already in that 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 an echo at the beginning of the cycle, it says that the values NM9 and NM10 are "1". Can you find the problem? I suspect it's the "VAR" part, or maybe some problem in assembling the lines. Thank you.

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 is called only variables outside the IF condition and FOR p>      

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   that is, a variable %VAR% will look like this: !VAR!

     

Make changes, test the code and comment here   Right, blz?
