This is written in "NT Batch". A simple line-driven "language" used by the Windows command environment. I say language in quotes because it's not actually a language. It's a series of commands that are stored in a text file and executed together, in order as a means of automating a process or sequence of commonly used commands.

It is often (incorrectly) referred to as a language because Microsoft has added some additional commands that allow you to perform some simple logic within batch files.

Ths.. Bro.. can i get any PDF to know this simple program, because now i want to write small scripts to copy data from remote server to my PC. can u tell me which script is easy to learn because i don't know more programming..i need to learn and need to develop.. and if possible can u give me the link to download the PDF.

Thanks in advance.

I started out learning DOS batch programming and LiSP coding for autocad. I'm slowly learning more, but I believe you are on the right track. Especially where you want to learn it.
I would start with a simple search on the Web for 'DOS batch commands' & 'MSDOS programming'. This is what I found:
DOS batch commands
DOS batch commands
DOS batch commands
MSDOS programming

There is a lot of info out there about DOS commands and programming it.
I also have some code I would happily share with you if you are interested in learning some of it here.
