Sequential renaming batch file

[jalbes]

I'm trying to make a batch file and I'm not having any luck.

I have a template file called:
BORDER TEMPLATE.dwg

I want to copy this file and rename it 42 times to this:
LOT 1 CHELTENHAM ESTATES PLOT PLAN.dwg
LOT 2 CHELTENHAM ESTATES PLOT PLAN.dwg
...
LOT 42 CHELTENHAM ESTATES PLOT PLAN.dwg



Now, I found this code somewhere, and it looks like what I need, but when I run the bat file, only one file gets created and I get an error saying that XSET is not a recognized command. Any idea how I can rectify this?

:: SEQ.bat
:: Copies Files in Sequential Order
:: Makes 42 Copies
::
@ECHO OFF

SET NUMBER=1

:AGAIN
COPY "G:\Drawings\CHELTENHAM ESTATES\PLOT PLANS\BORDER TEMPLATE.dwg" "G:\Drawings\CHELTENHAM ESTATES\PLOT PLANS\LOT %NUMBER% CHELTENHAM ESTATES PLOT PLAN.dwg"  > NUL

XSET /MATH NUMBER=%NUMBER% + 1
IF NOT "%NUMBER%" == "42" GOTO AGAIN

:END
SET NUMBER=

Problem solved.

I had to download XSET - shareware program and put the files into the same directory as the bat file.

Works like a charm!
