Batch file variable

Question

I have this code which echo the variable name...

set filename=
set filename=%1

... where %1 is a command input from cmd

However when I run this batch file again which a different input, it still has the same value as before. When I run it again, then it has the value previously entered. How do I clear the variable so when I run the program again, it receives that input rather than the one before?

Is this fragment of code by any chance contained in an IF statement or, perhaps, in a loop body? — Andriy M

I would write it like so:

@echo off
setlocal
::set filename=
set "filename=%1"
pause

That should work.
