@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

if m geq %1 goto :eof

%m%

可用以下代码：

for /l %%i in (1 1 77) do (set/p== <nul)
for /l %%i in (1 1 78) do (set/p=<nul)
for /l %%i in (1 1 77) do (set/p=^><nul&ping -n 1 127.1>nul)

晕到，这么简单都没看见
