In pure DOS mode, the following statements can't be used: set /p confrim=yes or no?(y/n): if %confirm% == y goto .. if %confirm% == n goto.. That is, wait on the screen to get a variable entered by the user. I know I can use CHOOSE, but it's an external command. I'd like to know what other methods there are to achieve the function above.

set /p confrim=yes or no?(y/n): if %confirm% == y goto .. if %confirm% == n goto.. This can do it, but there is one problem: if the user enters some other character, then %confirm% is neither equal to Y nor equal to n. So add another bit of code: :re set /p confrim=yes or no?(y/n): if /i %confirm% == y goto .. if /i %confirm% == n goto.. if /i %confirm% neq y goto :re if /i %confirm% neq n goto :re
