You can use the Python function raw_input():

	@ resp = raw_input("Proceed (y/N)? ")

You can use a loop to keep asking until a valid answer is given.  You
can find an example in the modules/d.aap recipe:

        @r = " " 
        @while not r == '1' and not r == '2': 
            :print 1. Become root/administrator and install in the Aap binaries
                        directory.
            :print 2. Specify another location to install ddepcheck.
            :print q. Quit
            @r = raw_input("Select an option: ")
            @if r == '1':
                :asroot $dc -O -of$bindir`os.sep`ddepcheck$EXESUF 
                            $toolsdir`os.sep`ddepcheck.d
            @elif r == '2':
                :print The path entered must be writable from your user.
                @bindir = raw_input("Enter install path for ddepcheck ")
                :sys $dc -O -of$bindir`os.sep`ddepcheck$EXESUF 
                        $toolsdir`os.sep`ddepcheck.d
                :print NOTE: It might be necessary to add $bindir to your PATH 
                        before the next execution of Aap.
                _top.DDEPCHECK = $bindir`os.sep`ddepcheck$EXESUF
            @elif r == 'q':
                :quit
