Answer» 1)In a batch file command i see this:
%1
what is it?
it was WRITTEN that:
The percent FOLLOWED by a NUMERIC value, BEGINNING with one, allows users to add variables within a batch file. The following is a batch file example:
echo Hello %1
i didn't understand the meaning. Pls explain. What does it mean by a variable?
2) also it was written " This can be extended to %2, %3, and so on"
How to do that???
Thanks in advance.
Actually the variables %0 THRU %9 are values that are passed along the command line when running a command or file.
%0 is always the name of the command or file you're running
Ex: copy frompath\filename.ext topath\filename.ext
%0 = copy (the name of the file or command)
%1 = frompath\filename.ext
%2 = topath\filename.ext
There is also a SHIFT command that allows you to manipulate the values and extend them beyond %9.

Hope this helps.
