@echo off
set b==
set b1=-
set m=1
call :w 80
call :s
exit
:w
set /a m+=1
set b=%b%=
if m geq %1 goto :eof
goto w
:s
cls
set b=%b:~1%
set b1=%b1%-
for /l %%i in (1,1,25) do echo\
echo windows 2000 loading......
echo\
echo %b1:-=^>%%b%
set /a n+=1
if %n%==79 goto :eof
ping 1.1 -n -w 50>nul
goto s
为什么echo %b1:-=^>%%b%中变量B为何没有保存80个等号
请给指正，谢谢
