Weird arithmetic error in a simple script

[Lamcourt]

Hello,
I have a very singular issue with this script :
@echo off
set /p L=L?
set /p l=l?
set /a s=%L%*%l%
echo s = %s%
pause
If L=5 and l=4, it gives me 16 as a result !!!! (L stands for Large and l stands for lentgh )

But if I replace L and l by a and b, it works perfectly

How comes ???

Thx a lot

Environmental variables are NOT CASE SENSITIVE!

But remember that FOR variables are case sensitive.

L stands for Large and l stands for lentgh

The unmeasurable question: if you want that one variable stands for Large and the other one for length, why don't you name them "Large" and "length"? Variable names may be many characters long. Please, do not ask how many characters a variable name can have!
