"Counter" in Batch
I'm Trying to Make a Batch File That Will Increment a Variable by 1 Each Time It Loops, and Then Check If the Variable Is Equal to 5, and If It Isn't, It Loops...
I'm trying to make a Batch file that will increment a variable by 1 each time it loops, and then check if the variable is equal to 5, and if it isn't, it loops again. I know there's probably a while loop for this, but I didn't know how to do that, and I'm just enjoying learning Batch for fun right now
Here's the code, it doesn't work the way it should, it just displays a 0: and then does nothing else. So how would I go about fixing it? I have a feeling I'm setting and incrementing the variable wrong, and maybe it's confused about the 2 if statements? (Does it have an else if....?) Anyways, thanks for the help
@echo off
set /p i=0:
goto A
:A
set /p i=i+1:
if i != 5 goto C
if i == 5 goto B
:C
echo Test :D
:B
pause>nul
Note: I don't know a lot of Batch and I'm not a pro, but I like to learn and I'm just doing this for future reference, and because I enjoy it. So, this code probably isn't good, but I want to know how I can accomplish this.

This is a way to simulate the while loop you are trying to accomplish. Only one goto is needed:
@echo off
set /a x=0
:while
if %x% lss 5 (
echo %x%
pause>nul
set /a x+=1
goto :while
)
echo Test :D
You can do that with a simple FOR command :
for /l %%x in (0,1,100) do (
echo %%x
)
You can replace 100 by the number you want
To set a numerical value to a variable, you may use the /a switch:
The /A switch specifies that the string to the right of the equal sign is a numerical expression that is evaluated.
(Type SET /? for all the help).
Second, check your goto flow - this never loops back to A.
Third, check the syntax of the if expression (!= doesn't exist in batch).
This should work:
@echo off
set var1=0
:loop
set /a var1=%var1%+1
echo %var1%
if %var1% EQU 5 (
goto :end
) else (
goto :loop
)
:end
pause
@echo off
set a=0
:Count
set /a a=a+1
echo %a%
goto Count
try this:
@if (@CodeSection == @Batch) @then
@echo off
:a
cls
color c
echo --------------
echo start:
echo --------------
set /p start=
cls
echo --------------
echo start: %start%

echo stop:

set /p stop=
cls

echo start: %start%

echo stop: %stop%

timeout /t 2 /nobreak >nul
echo. 5
