Thanks William Roeder,

for %A in (1,1,5000) do echo ..regno=%A^&year= >>file.txt

this command creat file  but there is only three lines list
as follows:
..regno=%1&year=.
..regno=%1&year=.
..regno=%5000&year=.

not all 5000 lines
and
for /l %A in (1,1,5000) do echo ..regno=%A^&year= >>file.txt

not working it comes "syntax error"

I am using the Windows ME
