Syntax error in For loop of batch script

I don't understand why this keeps returning syntax errors. Can somebody take look and tell me how I can get it to correctly work.

for /L %%n in (1, 10, 100, 1000, 10000, 100000) do ( test.exe %%n )

To answer your followup question, just add parentheses to add more commands in a loop.

@echo off
for /l %%N in (0 10 100) do (
   echo ======[A]======
   echo %%N
   echo ======[B]====== 
)

If you want to iterate a list of values, then you want a simple FOR with no option:

@echo off
for %%N in (1 10 100 1000 10000 100000) do echo %%N

result

1
10
100
1000
10000
100000

If you want to iterate a range of numbers, then use the /L option. The IN clause requires three arguments - startValue, Increment, and endValue

@echo off
for /l %%N in (0 10 100) do echo %%N

result

0
10
20
30
40
50
60
70
80
90
100

Your code with the /L option and 6 values in the IN() clause is invalid

FOR /L syntax is for /L %%x in (start,step,end) do which sets %%x to start for the first loop, alters it by step for each loop until it reaches end.

remove the /L if you want to run test.exe with the contents of a list.
