(1)、拷贝文件:
type file1 〉file2 ;产生 file2 文件
type file1 〉〉file2 ;在 file2 文件后追加
(2)、建立文件:
echo numLine = 10 〉starts.bas
echo For i = 1 To numLine 〉〉starts.bas
echo theStr = ""〉〉starts.bas
echo For j = 1 To 2 * i - 1 〉〉starts.bas
echo theStr = theStr + "*"〉〉starts.bas
echo Next 〉〉starts.bas
echo ? Space(numLine - i) + theStr 〉〉starts.bas
echo Next 〉〉starts.bas
(3)、输出到打印机:
copy starts.bas 〉prn
或 copy starts.bas 〉lpt1
type file1 〉file2 ;产生 file2 文件
type file1 〉〉file2 ;在 file2 文件后追加
